Effects of reversion and recrystallization on microstructure and mechanical properties of Nb-alloyed low-Ni high-Mn austenitic stainless steels

The influence of reversion annealing on the microstructure and mechanical properties of an austenitic high-Mn low-Ni 15Cr–9Mn–1.1Ni–1.7Cu stainless steel with and without Nb alloying was investigated. The steel sheets were cold rolled to a 60% thickness reduction to obtain about 60% of strain-induced α'-martensite and subsequently annealed at temperatures between 700 and 1100 °C for 0.1–1000 s in order to revert the α'-martensite back to...
