WebAbstract High-alloy CrMnNi TRIP/TWIP steels show a martensitic phase transformation, which is frequently described by the transformation sequence from ϒ-austenite (fcc) via ɛ−martensite (hcp) to α−martensite (bcc). During the plastic deformation, deformation bands in austenite are formed, which contain a high density of stacking faults on the lattice …

Electron Beam Melting of Metastable Austenitic Stainless Steel

WebAbstract . A new generation of high alloyed cast CrMnNi-TRIP-steels was developed exhibiting high strength (UTS) as well as high uniform elongation for a maximum of energy-absorption. The nature of the high elongation is the formation of .-martensite in the most deformed areas of the me tastable austenitic steel, so that necking is de-layed.
