Abstract
A dilatometric investigation was conducted to determine the individual effects of carbon, nickel, chromium, manganese, silicon, molybdenum, and cobalt on the volume expansion accompanying the martensite transformation in Fe-C and Fe-C-X alloys. It was found that the effects of alloying elements on the volume expansion measured at the Mₛ temperature can be expressed as the sum of two factors: first, a "temperature factor" that is positive for elements that lower the Mₛ and negative for cobalt, which raises the Mₛ; and second, a "lattice parameter factor" that is positive for austenite stabilizing elements and negative for V-loop formers. From these data, an empirical equation was developed that can be used to predict the volume expansion of ferrous alloys at their Ms temperatures.
