  • Austenite Martensite Bainite Pearlite and Ferrite structures

    M s can occur over a wide range, from 500°C to below room temperature, depending on the hardenability of the steel. The range M s to M f is typically of the order of 150°C. Many formulae have been proposed to predict the martensite start temperature. Most are based on the composition of the steel, and a selection are listed in the following ...
