Abstract: The effect of quenching temperature1025~1125℃+570℃4 h air cooling + 720 ℃ 2 h air cooling and secondary tempering temperature 680~780 ℃ after1050~1075 ℃ quenching on mechanical properties of martensite heat resistant steel X12CrMoWVNbN10- 1- 1(%:0. 11C,10.28Cr,0.77Ni,1.0Mo,0.96W,0. 18V,0.04Nb,0.053N) has been studied. Results show that with increasing quenching temperature,the strength of steel increases,of which the plasticity has no appreciable change,but the impact toughness obviously decreases; with increasing tempering temperature, the strength of steel decreases,while the plasticity and impact toughness of steel increase. The optimizing heat treatment of the steel is1050~1075℃1~2h oil cooling +570℃4h air cooling +715~725 ℃ 2 h air cooling.
摘要: 研究了淬火温度1025~1125℃+570℃4 h空冷+720℃2 h空冷和1050~1075℃淬火后二次回火温度680~780℃对马氏体耐热钢X12CrMoWVNbN10-1-1(%:0.11C、10.28Cr、0.77Ni、1.0Mo、0.96W、0.18V、0.04Nb、0.053N)力学性能的影响。结果表明,随淬火温度的提高,钢的强度增加,塑性变化不大,但冲击韧性显著下降。随回火温度的提高,强度下降、塑性、韧性增加。该钢优化的热处理工艺为:1 050~1 075℃1~2 h油冷+570℃4 h空冷+715~725℃2 h空冷。
