Paper Abstract
A Ginzburg-Landau free energy model of multivariant phase transformation in shape memory alloy has been developed. This paper is focused on linking the developed microscopic model with the atomistic reordering process which finally give rise to self-accommodating microstructure. It is analyzed how the kinetics influences the computation of stress-temperature induced dynamics of
phase transformation in microscopic and larger length-scales without attempting to solve a molecular dynamic problem in a coupled manner. A variational approach is adopted and phase transformation in Ni-Al thin film is simulated. The simulations capture a qualitative picture of the onset of microstructure formation.
