摘要：
The effects of B on microstructure, tensile properties, fracture behavior and phase transformation in 13% Mn metastable austenitic steels were systemically investigated. B addition increased the yield strength for the existence of hard borides, but reduced the total elongation because of different fracture mechanisms caused by the brittle borides. Microstructural analysis indicated that the excellent mechanical properties were the results of the combination of transformation induced plasticity (TRIP) and twinning induced plasticity (TWIP) effects. Meanwhile, the highly concentrated stress at the ends of cracked borides induced the transformation from austenite to martensite and a large amount of austenite were consumed by this way, which led to the earlier occurrence of fracture.
