摘要(Abstract)：

采用光学显微镜、扫描电镜、X射线衍射仪和冲击试验机等研究了不同随炉冷却温度(900、920、940和960℃)对TC10钛合金微观组织与冲击性能的影响。结果表明：经不同温度随炉冷却处理后，TC10钛合金组织中的α相形貌、分布以及尺寸均产生了较大的变化；随着随炉冷却温度的升高，TC10钛合金组织中的等轴α相含量逐渐减少并消失、条状α相含量与尺寸则不断增加，且出现晶界α相，合金的冲击性能不断降低；随炉冷却温度较低时(900和920℃),TC10钛合金的冲击断口上可观察到大量尺寸较大的韧窝，随炉冷却温度升高后(940和960℃),冲击断口中的韧窝尺寸以及数量减少，出现明显的撕裂棱，且断口中出现空洞以及二次裂纹。
