摘　　要：通过对G105钻杆材料热处理工艺试验,研究不同回火温度对材料组织的影响,并利用电化学测试和慢应变速率拉伸试验分析G105钻杆材料在不同热处理条件下的组织和性能变化对其腐蚀性能的影响。结果表明:采用890℃淬火+620℃回火、890℃淬火+580℃回火热处理后,材料性能能够满足G105钻杆技术要求;回火温度影响材料的力学性能,回火温度越高材料的塑性及韧性越强;采用890℃淬火+620℃回火处理后的显微组织优于890℃淬火+580℃回火工艺,并具有更佳的抗腐蚀性能。Based on the heat treatment process test of G105 pipe materials,the influence of different heat treatment on material microstructure and properties was studied by using electrochemical test and slow strain rate tensile test.The results show that material properties can meet the need of G105 pipe technical requirements after quenched at 890℃and tempered at 620℃or quenched at 890℃and tempered at 580℃;tempering temperature impacts the mechanical properties of materials,and the higher the tempering temperature,the stronger the ductility and the toughness;the microstructure after quenched at 890℃and tempered at 620℃is superior to that quenched at 890℃and tempered at 580℃,and the former has better corrosion resistance.
