Materials Science for Engineering Students offers students of introductory materials science and engineering, and their instructors, a fresh perspective on the rapidly evolving world of advanced engineering materials. This new, concise text takes a more contemporary approach to materials science than the more traditional books in this subject, with a special emphasis on using an inductive method to first introduce materials and their particular properties and then to explain the underlying physical and chemical phenomena responsible for those properties. The text pays particular attention to the newer classes of materials, such as ceramics, polymers and composites, and treats them as part of two essential classes — structural materials and functional materials — rather than the traditional method of emphasizing structural materials alone.

Materials have been central to the growth, prosperity, security, and quality of life of humans since the beginning of history. Only in the last 25 years, and especially in the last decade, has the intellectual foundation of the field that we call materials science and engineering begun to take shape and to achieve recognition.

This has occurred just as the field itself is expanding greatly and contributing significantly to society. Without new materials and their efficient production, our world of modern devices, machines, computers, automobiles, aircraft, communication equipment, and structural products could not exist. Materials scientists and engineers will continue to be at the forefront of these and other areas of science and engineering in the service of society as they achieve new levels of understanding and control of the basic building blocks of materials: atoms, molecules, crystals, and noncrystalline arrays.

The fruits of the efforts of materials scientists and materials engineers over years and decades can be illustrated by literally hundreds of examples, and those few given below are but an inescapably arbitrary selection. The strength-to-density ratio of structural materials has increased dramatically throughout the industrial age Figure 1.

Modern advanced materials are approximately 50 times better than the cast iron of two centuries ago in this important engineering measure. To suspend a ton weight vertically from the end of a cast iron rod would require a rod with a cross. To suspend the same weight from a modern high-strength polymer fiber would require a fiber with a cross section of 0.

We experience the results of these advances every day, for example, in household appliances that are lighter and more efficient, in eyeglasses that are more comfortable, and in automobiles and airplanes that use less fuel and go faster.

The efficiency with which heat energy is converted to mechanical or electrical energy in engines and power plants is another engineering measure important to society. This efficiency depends directly on the temperature at which the device can operate well; thus materials that are strong at high temperatures are desired.

The maximum theoretical efficiency of such engines is about 80 percent, whereas the efficiency of conventional engines is limited to about 60 percent.

The ultimate result is more efficient production of energy. Before about the mids, the only permanent magnetic materials available were special steels. Modest improvements in the magnetic strength of these materials were made, but significant increases came only with the development of aluminum-nickel-cobalt alloys in the s and s. Today, permanent magnets have magnetic strengths more than times greater than those available at the turn of the century Figure 1.

These and other magnetic materials are making possible smaller, more powerful motors and better and smaller sound systems, and they are carrying out many other hidden tasks in modern machines and devices. Superconductivity was first discovered in Then, beginning in , working with entirely new classes of materials, researchers developed a material with a superconducting transition temperature of Note: RE, rare earth. Rapid progress in developing materials with even higher transition temperatures culminated in the present record of K Figure 1.

This discovery not only is of great scientific interest, but it also promises to have a significant practical impact in a wide range of fields.

The technical difficulties that prevent the general use of these materials today are precisely those connected with synthesis and processing that contribute the principal challenge to materials science and engineering as a whole.

Scientists and technicians improved the transparency of silica glass slowly over the centuries from B. Today, these fibers are some orders of magnitude more transparent than they were in Figure 1. A single glass fiber 0. Even for abrasives and cutting tool materials, it is possible to find significant, often exponential increases in the performance of materials.

Figure 1. The result is far more efficient manufacturing processes that lower the costs of goods we buy. In integrated electronic circuits, the number of components per chip has increased at exponential rates since about Figure 1.

This increase has been achieved partly through steady reductions in line widths through continuing improvements in photolithography Figure 1. Integrated circuits, in turn, have led to computers and electronics that have revolutionized our lives.

This achievement is a triumph for both materials scientists and materials engineers, who have mastered the complex interacting relationships between phenomena, materials, and processing. Innovations in materials processing have had enormous impacts on the factory floor. In the steel industry, for example, the average worker can now produce 6 times as much steel per hour as he could in the s Figure 1. Adapted from M. Tesaki and H.

Materials science and engineering influences our lives each time we buy or use a new device, machine, or structure. Some examples of developments now emerging from our laboratories include the following:. What is the nature of materials science and engineering, a field that so profoundly affects the quality of our lives in so many different ways?

The intellectual core and definition of the field stem from a realization concerning the application of all materials: whenever a material is being created, developed, or produced, the properties or phenomena the material exhibits are of central concern.

Experience shows that the properties and phenomena associated with a material are intimately related to its composition and structure at all levels, including which atoms are present and how the atoms are arranged in the material, and that this structure is the result of synthesis and processing. The final material must perform a given task and must do so in an economical and societally acceptable manner.

It is these elements—properties, structure and composition, synthesis and processing, and performance and the strong interrelationship among them—that define the field of materials science and engineering.

These elements and their relationships are shown schematically in Figure 1. In developing new materials, it is difficult to anticipate where seeking knowledge ends and applying it begins. Hence science and engineering are inextricably interwoven in the field of materials science and engineering. It draws on areas as diverse as quantum mechanics on the one hand and societal needs, including manufacturing, on the other.

A proper perspective from which to consider the field requires understanding of the roles of science and engineering and their synergies. At the science end of its spectrum, materials science and engineering is rooted in the classical disciplines of physics and chemistry. Condensed-matter physicists, solid-state chemists, and synthetic chemists form the bridge between fundamental science and a subset of that science on which modern materials science and engineering rests.

These sciences aim to increase knowledge, and especially understanding, of structure, phenomena, behavior, or synthesis. Very often, the stimulation for this group to follow a particular direction of research may come from a technical problem. But the most important advances typically have been made when the research has been placed in a broad context and has been allowed to follow directions whose promise may not have been apparent at the outset.

Earlier in this century, the discovery and understanding of dislocations in crystals revolutionized our understanding of the strength of materials and led to the development of vastly improved structural materials. Understanding of the electronic structures of semiconductors, especially how they are influenced by impurities and in the vicinity of a surface, led to the development of the transistor and, subsequently, to the integrated circuit, which led to the microelectronic revolution. This discovery, in turn, led to a variety of solid-state lasers, which are used in communication and in information storage.

In three consecutive years—, , and —three great advances in fundamental materials science were recognized by the awarding of Nobel Prizes:. In , in the course of fundamental studies of electrons moving in semiconductor surfaces, an entirely new and unexpected effect, the quantum Hall effect associated with almost total absences of electrical resistance , was discovered Figure 1. It should be noted that this research was certainly stimulated in part by the enormous technical interest in electrons near semiconductor surfaces.

The experiments were entirely dependent on recent progress in materials science and engineering, which had made possible the preparation of surfaces with extremely well-controlled properties. The full implications of the Hall effect for our understanding of the dynamics of surface electrons are still being developed.

In the early s a radically new type of microscope, the scanning tunneling microscope, was developed. It depended on a subtle quantum mechanical effect, the tunneling of electrons below the tops of barriers an event that could not happen under the laws of Newtonian mechanics.

This technique led to incredibly accurate information about the positions of individual atoms on surfaces Figure 1. Displacements of the order of 1 percent of the normal interatomic distance can be detected with the scanning tunneling microscope. Superconductivity was discovered in in mercury, which lost all electrical resistance below 4. By the early s, a painstaking materials science effort lasting more than 60 years had led to metallic compounds that remained superconducting at up to 23 K, an average increase of about 0.

No further progress occurred until , when researchers studying entirely different classes of compounds discovered superconductivity at up to 39 K. Since then, based on accumulated knowledge of materials, compounds have been developed that remain superconducting at up to K. Although major materials problems remain to be overcome e. Breakthroughs such as these cannot be predicted or planned, but the environment conducive to their continued occurrence can be. It requires sustained support for and commitment to the basic science that undergirds materials science and engineering.

Semiconductor devices and integrated circuits would never have been developed if both science and engineering had not been understood; the development of a room-temperature laser required an understanding of semiconducting phenomena and structure e. Similarly, building and processing of modern composite materials require an understanding of surface science and molecular bonding as well as a strong engineering foundation. Future development of superconducting materials is also essentially dependent on materials science and engineering because such advances require expertise in understanding materials phenomena and their relationship to structure and defects in the structure, to processing which influences the structure , and to other properties such as brittleness and susceptibility to environmental degradation.

The general approach to solving materials problems for applications came from metallurgists. It was first used at the turn of the century and continued to develop as the relationship between structure, properties, and performance of metals was clearly established. Over time, the important role of processing. The critical role of processing is a central theme of this report. Today, relationships between structure, properties, performance, and processing are understood to apply not only to metals, but also to all classes of materials.

Thus modern materials engineering involves exploitation of relationships among the four basic elements of the field—structure and composition, properties, synthesis and processing, and performance i. Some important materials discoveries have been made by scientists, some by engineers, and still others by craftsmen.

Many have been made by teams comprising all three types of individuals. Today, craftsmanship alone, in the absence of modern science and engineering, rarely suffices to bring about a new development in materials. Craftsmanship alone is also increasingly inadequate with respect to processing or production of materials.

A crucial challenge for the future is to find ways of carrying out education, research, and engineering—including production—that encourage the maximum interaction among scientists and engineers, among mathematicians, physicists, chemists, and biologists, and among the four basic elements of materials science and engineering. Supporting such interactions is a difficult task requiring much wisdom, and, realistically, a willingness to make tradeoffs.

But progress in accomplishing this task is both possible and essential. Materials scientists and engineers study the structure and composition of materials on scales ranging from the electronic and atomic through the microscopic to the macroscopic. They develop new materials, improve traditional materials, and produce materials reliably and economically through synthesis and processing.

Since the beginning of history, materials have played a crucial role in the growth, prosperity, security, and quality of human life. In fact, materials have been so intimately related to the emergence of human culture and civilization that anthropologists and historians have identified early cultures by the name of the significant materials dominating those cultures. These include the stone, bronze, and iron ages of the past. At the present time, the scope of materials science and engineering has become very diverse; it is no longer confined to topics related to metals and alloys but includes those relevant to ceramics, composites, polymers, biomaterials, nanostructures, intelligent materials, and electronic devices. In addition, present activities in materials science and engineering cover not only areas whose utility can be identified today, but also areas whose utility may be unforeseen.
