Abstract

Self-organization processes that determine the response of a system to strong external influences are investigated. Explosion welding and torsion under pressure are selected as such influences. Emphasis is placed on analyzing the self-organization processes that occur during explosion welding, including aspects related to mechanisms that determine the cohesion of contacting materials. The evolution of the dislocation structure of Ni3Ge intermetallic is also observed with torsion under pressure. It is found that torsion makes automatic blocking impossible upon subsequent unloaded heating, and the reason for the disappearance of automatic blocking is determined.
