GW01铝合金是在6061铝合金基础上研发的一种新型高强铝合金。采用三因素三水平的正交实验，研究了固溶温度-时间、时效温度、时效时间三因素对GW01铝合金T6处理后力学性能的影响规律。结果表明：随着固溶温度的提高和固溶时间的缩短，GW01铝合金的抗拉强度、屈服强度和硬度均有大幅度提高，其伸长率则先降低后升高；随着时效温度的升高，GW01铝合金的抗拉强度、屈服强度、硬度以及伸长率均不断降低；GW01铝合金的抗拉强度、屈服强度以及硬度均对时效时间不敏感，随时效时间的延长只有小幅度的降低，其伸长率则随时效时间的延长有一定幅度的提高。(510 ℃，3 h，水淬)+(170 ℃，18 h，空冷)的T6热处理可以使GW01铝合金管材获得良好的综合力学性能。
GW01 aluminum alloy is a new type of high-strength aluminum alloys researched and developed based on 6061 aluminum alloy. The effects of solid solution temperature-time, aging temperature and aging time on mechanical properties of GW01 aluminum alloy after T6 treatment were investigated by orthogonal experiment of three factors and three levels. The results show that, with the solution temperature increasing and solution time decreasing, the tensile strength, yield strength and hardness of GW01 aluminum alloy are improved greatly, and the elongation increases after a certain amount of decline. With the aging temperature increasing, the tensile strength, yield strength, hardness and elongation of GW01 aluminum alloy decrease constantly. The tensile strength, yield strength and hardness of GW01 aluminum alloy are all insensitive to aging time, which means that they only decreases a little with aging time extending. The elongation increases with aging time extending. The good mechanical properties of GW01 aluminum alloy pipe are obtained after T6 treatment process of (510 ℃, 3 h, water quenching)+(170 ℃, 18 h, air cooling).
