CONTRIBUTION TO PHYSICAL METALLURGY OF NEW HIGH STRENGTH Mn MATERIAL

Popis výsledku v původním jazyce

In the automotive industry significant process has been achieved concerning safety and fuel economy. High manganese materials form perspective generation of ductile high strength alloy. Extraordinary mechanical properties of these alloys named FeMnTWIP1100 (twinning induced plasticity) basically come from two main features: a) material is fully formed with the FCC structure at all considered temperatures b) twinning is the main deformation mechanism. The FeMnTWIP alloys possess low stacking fault energy(SFE) leading to the possibility of multiple simultaneous and/or sequential deformation mechanisms. In addition to dislocation slip, both mechanism twinning and -martensite formation are concurrent deformation mechanisms linked to the SFE. The boundaryvalue of those parameters is 18mJm-2. At the SFE level, being higher than presented critical value (around 20 25mJm-2 usually) -martensite is not initiated. The twinning deformation acts as the decisive mechanism contributing to the achie
