Influence of Hardening Phase of Coherent and Incoherent Coupling with FCC Matrix on Evolution of Deformation Defect Subsystem and Strain Hardening of Heterophase Alloys

Abstract:

A mathematical model of plastic deformation of dispersion-hardened materials with FCC matrix and strengthening particles having various coupling with the matrix is presented. The model is based on the equations of balance of deformational defects of various types with allowance for their transformation in the process of plastic deformation. The influence of scale characteristics of the strengthening phase, temperature, and strain rate on the evolution of the dislocation subsystem and on strain hardening of an alloy with FCC matrix is investigated.
