摘　　要：研究了950~1 200℃固溶处理对UNS N06625合金冷轧管组织和力学性能的影响。结果表明,当固溶温度从950℃提高至1 200℃,屈服强度和抗拉强度分别从480 MPa和900 MPa降至380 MPa和810 MPa,伸长率由45%提高至57.5%;晶粒度级长大至4.0~7.0级;1 100℃以上固溶处理时,合金中的碳化物基本溶解;晶粒尺寸和析出相数量是影响UNS N06625合金强度的主要因素。The effect of solution treatment at 950-1 200℃on microstructure and mechanical properties of cold rolling tube of UNS N06625 alloy were investigated.The results indicate that with increasing temperature of solution treatment from950℃to 1 200℃,the yield strength and tensile strength of alloy decrease respectively from 480 MPa and 900 MPa to 380 MPa and 810 MPa,while the elongation of alloy increases from 45%to 57.5%and grain size increases 4.0-7.0grade;as solution treatment temperature is more than 1 100 ℃,the carbides in alloy dissolve completely.The grain size and the number of precipitated are critical factors for mechanical properties of UNS N06625 alloy.
