Molecular-Dynamics Simulation of the a-Ti Plastic Deformation Under Conditions of High-Energy Effects

摘要

Modeling of high-speed deformation of a-Ti at a pressure of 20 GPa and a temperature of 700 K simulating the conditions of high-energy effects is carried out. The mechanisms of plastic deformation, including sliding along prismatic planes and the a-ω transition, are established. A feature of the deformation process of titanium in the considered conditions, which leads to the formation of disperse inclusions of the a-phase in the ω-phase matrix, is revealed.
