| Abstract Scope |
We present an overview of the new PRISMS-MultiPhysics (PRISMS-MP) open-source, coupled phase field-crystal plasticity framework. We focus on two specific types of applications within the framework: 1) a publicly available application to model twin propagation, growth and transmission across grain boundaries and 2) an application under development to simulate dynamic recrystallization (DRX). As validation for our twinning application, we compare a simulated twin morphology to that of a Mg-4Al alloy twin reconstructed from 3D Dark Field X-ray Microscopy (DFXM) in situ experiment. In addition, we examine how, for Mg alloys, twin transmission depends on the incident twin propagation direction and grain boundary misorientation, and discuss our ongoing efforts to implement a method for twin nucleation in PRISMS-MP. For the DRX application, we discuss plans to simulate the recrystallization behavior of Mg-Zn-Ca alloys with different compositions, for which experimental data for validation are available. |
