- Resilience is the capacity of a material to absorb energy when it is deformed plastically, and then upon unloading, to have this energy recovered. TRUE / FALSE - Critical resolved shear stress represents the minimum shear stress required to initiate slip, and it is a function of the loading direction relative to the slip direction. TRUE / FALSE - Brittle fracture takes place without any appreciable deformation and by rapid crack propagation. TRUE / FALSE - Extrusion increases dislocation concentration. TRUE / FALSE - Recrystallization is the formation of a new set of strain-free and equiaxed grains that have low dislocation densities. TRUE / FALSE - A brittle material typically exhibits substantial plastic deformation with high energy absorption before fracture. True False - During the recovery of a cold-worked material, there is an increase in the number of dislocations. True False - As temperature decreases, the fraction of the total number of atoms that are capable of diffusive motion decreases. True False - Ductility is a measure of the degree of plastic deformation that has been sustained at fracture. TRUE / FALSE
