Anyone know where I can get this book online for free? It's old so I assume there should be a pdf somewhere but I can't find anything. Materials Science, the anticipated readership being students of structural and It is clearly important for design engineers to know the stress at which. Schaffer's "Science and Design of Engineering Materials, 2nd Edition" will now be complemented by an e-Text. An e-Text is pdf. files of the.
In addition, as we have seen in the case of the space shuttle, the materials selected must function together as a system. While each material is selected for specic properties to fulll a given need, the materials must also be capable of operating together without degrading the properties of one another. By understanding the similarities and differences among these classes of materials, you will be in a position to make intelligent materials choices that can meet the challenges of modern technology.
Why are materials arranged in the groups listed above? Many materials have similar atomic structures or useful engineering properties or both that make it convenient to classify them into these ve broad groups. It should be recognized that these classications are somewhat arbitrary and may change with new discoveries and advances in technology.
Composites, also sometimes called engineered materials, provide an excellent example of a new classication. These materials are made by combining other often conventional materials, using advanced technology, to obtain properties that could not be obtained from the existing classes of materials. In our discussion in this chapter and throughout the book we will emphasize that the properties of a material are related to its structure. We will deal with structure at many size scales ranging from the atomic scale 0.
In the next chapter we will see that the material structure on each of these size scales can be used to understand and explain certain materials properties.
While the properties of a material are related to its structure, it is important to understand that the way in which a material is processed affects the structure and hence the properties. As an example of this important concept, consider the dramatic effect that thermal processing can have on the properties of steel. If slowly cooled from a high temperature, steel will be relatively soft and have low strength.
If the same steel is quenched i. Finally, if it is quenched and then reheated to some intermediate temperature, it will have an excellent combination of strength and toughness.
While we will study this example in depth later in the text, the major point to be made here is that each of the three thermal processes has produced a different structure in the same material, which in turn gives rise to different properties. Each of the ve classes of materials, together with some elementary structure-property relationships, is discussed briey in the following sections. These regular repeating structures, known as crystals and discussed in detail in Chapter 3, give rise to specic properties.
Metals are excellent conductors of electricity, are relatively strong, are dense, can be deformed into complex shapes, and are resistant to breaking in a brittle manner when subjected to high-impact forces.
This set of mechanical and physical properties makes metals one of the most important classes of materials for both electrical and structural applications. Extensive and in some cases exclusive use of metals occurs in automobiles, airplanes, buildings, bridges, machine tools, ships, and many other applications where a combination of high strength and resistance to brittle fracture is required.
In fact, it is largely the excellent combination of strength and toughness i. However, signicant improvements have been and continue to be made as a result of advances in processing.
Two examples are: s Higher operating temperatures in jet engines have been attained through the use of turbine blades that are produced by controlled solidication processes.
The blades are made of alloys atomic-scale mixtures of atoms of nickel or other metals and are in wide commercial use. Improvements will continue as processes are rened through use of advanced sensors and real-time computer control.
An important reason for using PM processing is reduced fabrication costs. While some improvement in properties can be obtained through PM, a major benet is the reduced variation in properties, which will allow the operating loads to be safely increased. Reduced production costs through PM will continue to impact the aerospace and automotive elds.
Many but not all ceramics are crystalline, and frequently the nonmetal is oxygen, as in Al2 O3 , MgO, and CaO, all of which are typical ceramics. As a result there are no free electrons in ceramics. They are generally poor conductors of electricity, but are frequently used as insulators in electrical applications.

One familiar example is spark plugs, in which a ceramic insulator separates the metal components. Ionic and covalent bonds are extremely strong. As a result, ceramic materials are intrinsically stronger than metals. However, because of their more complex structure, the ions or atoms cannot easily be displaced as a result of applied forces.
Rather than bend to accommodate such forces, ceramics tend to fracture in a brittle manner. This brittleness generally limits their use as structural materials, although recent improvements have been made by incorporating ceramic bers into a ceramic matrix and other innovative techniques.
Ceramics rigid bond structure confers other advantages, including high temperature stability, resistance to chemical attack, and resistance to absorption of foreign substances.
They are thus ideal in high-temperature applications such as the space shuttle, as containers for reactive chemicals, and as bowls and plates for foods where surface contamination is undesirable.
Some ceramics are not crystalline. The most common example is window glass, which is composed primarily of SiO2 with the addition of various metal oxides. Great insight.
Very well written both as a textbook and as a reference source in interdisciplinary research. Admirable value for money. Used to generate lectures. Very practical approach.
Good section on costs. Excellent case studies and phenomenology.

It is helpful to have answers for the problems. It is one of those which one can say without any hyperbole that multiple copies of it should be in every engineering library. It must certainly be added to technical libraries. The Pergamon Press must be richly congratulated for bringing out this book by two of the most accomplished material scientists of today.These regular repeating structures, known as crystals and discussed in detail in Chapter 3, give rise to specic properties.
The principal quantum number n is associated with the boundary conditions on r. They can form the bases for useful and provocative class discussions.
The approach maps out the relationships that need to be represented within materials models, or when specific models do not exist, by measured materials data. Test plans for a new component are then formalized and executed and equivalency of the material tested to the quality requirements, specification, and ultimately the design curves, is then assessed. Camcorders also contain small.
