Microstructure and mechanical property regulation of hot-rolled Al-contained medium-Mn steel by double intercritical annealing

Usually，the initial microstructure of hot-rolled and quenched medium-manganese experimental steel is composed of lath martensite matrix and a small amount of tiny granular austenite， also existing apparent Mn-segregation bands. Using double intercritical annealing （holding 60 min at 750 ℃ followed b...
