IRREVERSIBLE PHASE TRANSITIONS IN STEEL

摘要

We present a mathematical model for the austenite-pearlite and austenite-martensite phase transitions in eutectoid carbon steel. The austenite-pearlite phase change is described by the Additivity Rule. For the austenite-martensite phase change we propose a new rate law, which takes into account its irreversibility. We investigate questions of existence and uniqueness for the three-dimensional model and finally present numerical calculations of a continuous cooling transformation diagram for the eutectoid carbon steel C1080.
