摘要:

采用不同的始锻温度和终锻温度对新型含铌汽车钛合金棒材进行锻造试验,并进行了力学性能测试与分析。结果表明:随始锻温度从970 ℃增加到1090 ℃、终锻温度从900 ℃增加到980 ℃,新型含铌汽车钛合金棒材的抗拉强度、屈服强度先增大后减小,断后伸长率变化幅度不大,其力学性能先提升后下降。与970 ℃始锻温度锻造时相比,1030 ℃始锻温度处理的新型含铌汽车钛合金棒材的抗拉强度和屈服强度分别增大了121和127 MPa,断后伸长率减小了1.6%;与900 ℃终锻温度锻造时相比,960 ℃终锻温度处理的新型含铌汽车钛合金棒材的抗拉强度和屈服强度分别增大了100和143 MPa,断后伸长率减小了1.4%。新型汽车含铌钛合金棒材的锻造工艺参数优选为:始锻温度1030 ℃、终锻温度960 ℃。

Forging experiments of a new niobium-containing titanium alloy bar used in car were conducted at different initial forging temperatures and final forging temperatures, and the mechanical properties were tested and analyzed. The results show that with the initial forging temperature increasing from 970 ℃ to 1090 ℃ and the final forging temperature increasing from 900 ℃ to 980 ℃, the tensile strength and yield strength of the new type niobium-titanium alloy bar used in car first increase and then decrease, the elongation after fracture changes slightly, so the mechanical properties first increase and then decrease. Compared with the initial forging temperature of 970 ℃, the tensile strength and yield strength of the new type of niobium-containing titanium alloy bar increase by 121 and 127 MPa respectively, and the elongation after fracture decreases by 1.6%. However, compared with the final forging temperature of 900 ℃, the tensile strength and yield strength of the new type of niobium-containing titanium alloy bar increase by 100 and 143 MPa respectively, and the elongation after fracture decreases by 1.4%. Finally, the optimum forging process parameters of the new type of niobium-containing titanium bar are initial forging temperature of 1030 ℃ and final forging temperature of 960 ℃.
