Evolution of Nanohardness of Binary Titanium-Based Solutions under High-Pressure Torsion

Abstract

Based on the phenomenological theory in the Landau approximation, a model has been developed to describe experiments on measuring the nanohardness of binary titanium-based solutions under high pressure torsion. Possible mechanisms for the appearance in the experiment of asymmetry of this quantity relative to the middle of the radius of a cylindrical sample are determined. Additionally, the behavior of the radial and angular components of nanohardness in the presence of a point defect in the material under study has been studied.
