This proposal intends to investigate two ideas relating to TRIP steels in one experiment. Firstly, in-situ cooling under constant elastic stress will be performed to determine the effect of stress on transformation kinetics and variant selection. Secondly, the influence the resulting microstructural features have on the mechanical properties will be investigated with in-situ loading. The results should yield invaluable information which can be exploited for improving the processing routes for TRIP alloys.
