Abstract

Although the medium manganese steel has a high value of the product of tensile strength and elongation, it has the disadvantage of low yield strength. To solve this problem, two Fe-Mn-Al-C steels with (Ti, Mo) and without (Ti, Mo) were designed to analyze the effect of microalloy elements on their microstructure and mechanical properties. The steels were annealed at different temperatures for 24 h to obtain a stable microstructure close to equilibrium. The addition of Ti-Mo increased the yield strength by 150–300 MPa, and the maximum increment in yield strength was achieved at an intercritical annealing temperature of about 610 ℃. The increase in yield strength is mainly attributed to grain refinement and precipitation hardening with the addition of Ti-Mo.
