..., and how they respond to applied stresses and strains. The chapter makes extensive use of graphics to illustrate crystal lattice structures and related concepts such as vacancies and interstitial sites, ion migration, volume expansion, antisite defects, edge and screw dislocations, slip planes, twinning...

... screw dislocations stacking sequence Problem 1: Low-Density Steels There is significant interest in developing low-density steels to reduce the weight of vehicles and hence their fuel consumption. One method is to dissolve light impurity atoms in Fe. Take a look at the first 20 elements...

... of line dislocation is the screw dislocation ( Fig. 2.8 ). The term screw dislocation is used because of the spiral surface formed by the atomic planes around the screw dislocation line. When a Burgers circuit is used to determine the Burgers vector of a screw dislocation, the vector is found...
