Microstructure and Mechanical Properties of Ferrite-Austenite Duplex Low Density Medium Mn Steel

摘要：

　　This study addresses the microstructure,plastic flow and fracture behavior of laboratory Al-containing medium Mn steels.After cold rolling and intercritical annealing,they present an unordinary bimodal duplex microstructure made of coarse ferrite grains and ultrafine duplex (ferrite + austenite) regions.Room temperature mechanical properties are not strongly sensitive to the annealing temperature.At lower temperature,plastic flow,fracture mode and sensitivity to brittle cracking have been related to the microstructure.
