Abstract
In mechanical engineering distortion means undesired alterations of size and/or shape of a workpiece. A typical cause for distortion are solid-solid phase transitions as they occur during the heat treatment of steel.
In my talk I will present a thermomechanical model of phase transitions in steel, show some applications in the heat treatment of steel and discuss possible optimal control approaches to compensate distortion.
