“…It has been proved that the strain induced transformation of austenite is retarded if the C content in it is high and as a consequence, the strain induced transformation lasts in a high strain region, which contributes to diffusing the strain concentration, resulting in a more uniform elongation. 21,22) A mathematical model evaluating the stability of retained austenite and describing the kinetics of strain induced martensite transformation has been proposed and the increase in the stability of retained austenite upon C content being increased has been quantitatively evaluated.…”

Lightening of automobile bodies is required from the viewpoint of saving energy which contributes to ameliorating an ecological problem. A useful means of doing this is the application of high strength steel sheets to automobile bodies. The inferior formability of high strength steel sheets in comparison with that of mild steel sheets, however, hinders their broad application. But in recent years, many high strength steel sheets with good formability have been developed using sophisticated physical metallurgy.In this paper, the recent development of modern high strength steel sheets is reviewed paying special attention to their physical metallurgy which realized the improvement of their formability.

“…The sustainable requirements of automotive industry are directed to the development of multiphase steels, and particularly to the development of TRIP steels. Employing the TRIP phenomenon is aimed to produce steels with higher strength and improved elongation and recently it has been the subject of many recent investigations [1][2][3]. The microstructure of these steels of typical composition consists of polygonal ferrite, lath bainite and significant amount of RA [4].…”

Experimental simulations of thermomechanical processing (TM) using press forging of Si-Mn TRIP (transformation induced plasticity) steel were performed. In order to rationalize the retained austenite (RA) volume fraction, six TM schedules were employed at experiment where different austenite conditioning was considered. The various multiphase structure characteristics were obtained after of TM processing, with different volume fraction of ferrite, bainite and RA. The modification of structural characteristics influenced the mechanical properties of TRIP steel. The present work also focuses on monitoring of RA transformation during mechanical incremental straining using in situ neutron diffraction technique. This method is used to characterize the kinetics of RA transformation and its stability during the straining.
