【Abstract】

SS-DTA is an efficient tool for analysing phase transformations of metals during actual thermal processing conditions.SS-DTA involves the implementation of the differential temperature profile between the measured temperature and the reference temperature for detecting any phase changes of the investigated material.In this paper,we applied and compared several data modelling techniques to obtain the reference curve for SS-DTA technique.These models include the polynomial model,the piecewise polynomial model,and the piecewise linear model.Tests on a stabilised grade stainless steel SUS 321 were constructed to evaluate the performances of the proposed techniques in comparison with the conventional reference curve estimation approach.
