Abstract

We have developed a method of studying the kinetics of metastable ε-martensite formation at low temperatures without interrupting the deformation process. This method is based on the sum and difference of γ-, ε-, and α-phase contributions to the electrical resistivity of the alloy. The ε-martensite content can be calculated from measurements of the resistivity of these phases, the resistivity increment of the alloy under deformation, and, by using a magnetometric method, the amount of ferromagnetic α-martensite.
