Abstract

The behavior of localized plasticity macrodomains is experimentally studied at the final stage of the plastic flow in going to necking and ductile fracture in fcc, bcc, and hcp materials. General features of the localization process at the stage of prefracture are found. They are a constant velocity of domains and their tendency to consistently move toward the focus of a bundle of straight lines in space-time diagrams. A correlation between the type of fracture and the kinetics of localized plasticity domains is established.
