Abstract The aim of the present study was to combine the beneficial influence of recovery annealing on plasticity and carbide precipitation on strength to simultaneously improve the plasticity and strength of the cold-rolled steel. A novel multi-alloying twinning induced plasticity (TWIP) steel bearing tungsten was designed. The microstructure and strength properties of the steel were investigated. It was observed that annealing at 400 °C with thermal stability of twins, annihilation of dislocations in addition to Fe21W2C6 precipitates, resulted in synchronous improvement of yield and tensile strengths and elongation of the cold deformed steel.

沉淀恢复退火同时提高新型合金钢的强度和塑性

摘要 本研究的目的是结合恢复退火对塑性和碳化物析出对强度的有益影响，同时提高冷轧钢的塑性和强度。设计了一种新型的含钨多合金孪生诱导塑性（TWIP）钢。研究了该钢的显微组织和强度性能。观察到在 400°C 下退火具有孪晶的热稳定性，除 Fe21W2C6 析出物外还消除了位错，导致冷变形钢的屈服强度和抗拉强度以及伸长率同步提高。
