Origin of Extended Tensile Ductility of a Fe-28Mn-10Al-1C Steel
Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science - Tập 40 - Trang 1520-1523 - 2009
Tóm tắt
Fully austenitic Fe-28Mn-10Al-1.0C steel with high stacking fault energy exhibited exceptionally high uniform elongations (85 to 100 pct) and total elongations (100 to 110 pct) at room temperature. The origin of such exceptional room-temperature ductility was rationalized in terms of strain accommodation mechanisms of reduction of glide plane spacing in Taylor lattice (TL) formation at low strains and TL rotation forming domain boundaries (DBs) and microbands (MBs) at high strains.
