摘要

Abstract

BSTRACTComparison on the kinetics of two different phase transformations

including phase transformation

after

deformation and phase transformation

during

deformation (i.e. dynamic transformation

DT)

reveals a new discovery that the transformation kinetics can be significantly enhanced in DT even under low driving forces. DT enables continuous generation of defects (e.g. dislocations) near the phase boundary

which can act as short-circuiting diffusion paths for atoms. The diffusivity of atoms is enhanced and the activation energy for the atom jump across the phase boundary is lowered under stress during DT

resulting in more pronounced grain growth as well as accelerated transformation kinetics.
