Abstract

Properties of shape memory alloys during phase transformation are strongly affected by the heating rate based on the kinetics of phase transformation. A new mathematical approach, named Linearity method, was developed for estimating the kinetic parameters and degree of phase transformation at different heating rates. This method was found to be more appropriate in estimating these properties than the existing Kissinger method. A specific heat capacity model considering the heating rate effect was also developed and validated against the experimental results. These estimated properties can be used for determining the behaviour of the materials applied upon heating at varying rates. © 2016 Elsevier Ltd
