摘要

研究了一种新研制的微合金化贝氏体钢经热锻、空冷、回火处理后的力学性能。锻态贝氏体钢的显微组织主要由粒状贝氏体和~ 20vol . %马氏体组成。在200℃回火之前,残余奥氏体的比例保持不变,超过200℃后,残余奥氏体的比例显著降低。随着回火温度的升高,合金的极限抗拉强度和总伸长率均降低,屈服强度和收缩率均降低。在200°C和400°C左右回火后,分别观察到冲击韧性的最大值和最小值。这些影响主要是由于马氏体/奥氏体成分的分解和马氏体中的回火作用。锻造贝氏体钢在200℃左右回火,强度和韧性结合良好,可与传统调质40Cr钢相媲美。因此,低回火处理结合锻后残余应力消除是进一步提高贝氏体锻造钢力学性能的可行方法。

Mechanical properties of a microalloyed bainitic steel after hot forging and tempering

Mechanical properties of a newly developed microalloyed bainitic steel were investigated after the hot forging, air cooling and tempering process. The microstructure of the as-forged bainitic steel mainly consists of granular bainite and ∼20 vol. % martensite. The fraction of retained austenite remains unchanged until tempering at 200 °C, above which it decreases significantly. The increase of tempering temperature leads to decreases of both ultimate tensile strength and total elongation but decreases of both yield strength and reduction of area. The maximum and minimum values of impact toughness were observed after tempering at around 200 and 400 °C, respectively. These effects are mainly attributed to the decomposition of martensite/austenite constituents and the tempering effects in martensite. The tempering of the forged bainitic steel at around 200 °C results in an excellent combination of strength and toughness, which is comparable to that of the conventional quenched-and-tempered 40Cr steel. Therefore, low-tempering treatment coupled with post-forging residual stress relieving is a feasible method to further improve the mechanical properties of the bainitic forging steel.
