Finite Element Simulation of Dislocation Based Plasticity and Diffusion in Multiphase Materials at High Temperature

en Limba Engleză Paperback – 8 oct 2020

A single-crystal plasticity model as well as a gradient crystal plasticity model are used to describe the creep behavior of directionally solidi?ed NiAl based eutectic alloys. To consider the transition from theoretical to bulk strength, a hardening model was introduced to describe the strength of the reinforcing phases. Moreover, to account for microstructural changes due to material ?ux, a coupled diffusional-mechanical simulation model was introduced.
