Abstract
A considerable research effort has been done in the field of cold rolled TRIP steels submitted to a two-step annealing cycle. After annealing, these steels contain retained austenite, which offers them superior mechanical properties required for specific applications in automotive industry. In the present work, a physically based microstructural model has been applied to describe the static stress-strain behaviour of phosphorus alloyed TRIP steel. The impact of the TiC precipitation on the static stress-strain behaviour for a Ti micro-alloyed TRIP steel was simulated. The model calculations were compared with experimental stress-strain curves. An excellent agreement between simulation and experimental data was demonstrated.
