摘要

The effects of aluminium on mcrostructure and mechanical properties in medium manganese steels were investigated in this study. It is found that addition of aluminium don't significantly change the micro-structure evolution during heat treatment process, aluminium can retard the precipitation of carbides in the following annealing, resulting in higher carbon content in several austenite. Though aluminium addition leads to a certain decline of tensile strength, the yield strength and elongation are neither decreasing significantly, especially the former is improved after heat treatment. Furthermore, the Al-bearing medium manganese steels can achieve optimal product of strength and ductility with austenization at 675℃ and short time (5 min) annealing, the excellent mechanical properties are strength ～880 MPa, total elongation ～39.3% and product of tensile strength to total elongation (Rm~*A_T) ～34.6 GPa%.
