The Essence of Materials for Engineers

Chapter 8

Deformation Versus Fracture: Different Mechanical Responses to Stresses

Learning Objectives

After careful study of this chapter, you should be able to do the following:

1.  Identify and describe the various criteria for the mechanical failure of materials or structures, including both deformation and fracture.

2.  a.   Explain the process of slip in single-crystal metals, including the reason slip occurs on closed-packed planes and in close-packed crystallographic directions (i.e., on preferred slip systems).

b.  Explain the role of dislocations in the slip process.

3.  Describe how slip is made more complicated in polycrystalline metals.

4.  Differentiate between cold and hot working of metals and explain the processes and effects ...
