Mechanical MetallurgyThis bestselling metallurgy text examines the behaviour of materials under stress and their reaction to a variety of hostile environments. It covers the entire scope of mechanical metallurgy, from an understanding of the continuum description of stress and strain, through crystalline and defect mechanisms of flow and fracture, and on to a consideration of major mechanical property tests and the basic metalworking process. It has been updated throughout, and optimised for metric (SI) units . End-of-chapter study questions are included. |
