Study on Phase Transformation Constitutive Behaviors of Shape Memory Alloy

Abstract:

Article Preview

Phase transformation temperatures of the SMA annealed at different annealing temperature were investigated through a series of DSC test. A new phase transformation model was proposed to predict the phase transformation and a numerical analysis was conducted to demonstrate the applicability of the new model. According to the result, phase transformation temperatures would be affected on annealing temperatures and the new phase transformation model would be applicable to predict the phase transformation under the stress-free state or the external stress state.
