Abstract Scope |
Medium Mn steels are potential candidates of the 3rd generation advanced high strength steels. One of the methods for enhancing the mechanical properties applied to medium Mn steel is quenching and partitioning (Q&P) process. In this research, room temperature quenching was introduced for simple Q&P process using Fe-0.2C-10Mn-2Al steel. The difference of tensile properties with different annealing histories and the effect of partitioning were investigated. To obtain diverse phase fractions, three different annealing temperatures, 700, 750 or 800 °C, were used. After annealing at 700 °C, the microstructure consisted of ferrite and austenite. In contrast, martensite and austenite structure was obtained from the other two annealing temperatures. Partitioning process was carried out in the temperature range of 100~300 °C, and the improvement of elongation was achieved by partitioning at 200 and 300 °C. The resulting tensile properties were comparable to those produced by conventional Q&P medium Mn steels. |
