Abstract
We present a phase field model to simulate the microstructure evolution during deformation twinning in tantalum. An order parameter, proportional to the shear strain, is employed to monitor the twinning process. The evolution of the order parameter is governed by a time-dependent Ginzburg-Landau equation, the parameters of which are determined by molecular dynamics with a model-generalized pseudopotential-theory potential. The twinning process is studied under a number of deformation conditions, and compared with the molecular dynamics counterpart.
