【摘要】 对TC10钛合金用不同固溶温度进行热处理,测试其冲击性能,并观察组织变化和断口形貌,研究了固溶温度对TC10钛合金冲击性能的影响。结果表明,随着固溶温度的提高,初生α相逐渐减少,当温度达到950℃后初生α相全部转化为β相,从断口形貌看,试样由韧性断裂转变为脆性断裂,冲击性能随热处理温度的提高先升高再降低,中间出现一段稳定的最高值。更多还原

【Abstract】 The impact properties of TC10 treated with different solid solution temperature were tested. The microstructure change and fracture morphology were observed. The effect of solution temperature on the impact properties of TC10 titanium alloy was studied. The results showed that with the increase of solution temperature,the primary α phase decreased,when the temperature reached950 ℃,all of the primary α phase changed into the β phase. From the fracture appearance,the specimen changed from ductile fracture to brittle fracture,impact properties changed with the temperature increased first and then decreased,a stable maximum valueappeared in the middle.更多还原
