The laser induced temperature field and the austenite formation kinetics in laser transformation hardening have been investigated. The relationship between laser processing parameters, important temperature field data, material properties, and the laser track geometry has been modelled by fitting suitable analytical model functions to numerical results. Using these functions the personal computer program GEOPT is able to compute, within a few seconds, those processing parameter values which yield the temperature-time cycle required for hardening and a prescribed or in a definable manner optimized geometry of the laser track pattern. Furthermore, relations between the quantities involved may be graphically represented.
