摘　　要：TC11钛合金在首次应用于某型飞机机轮刹车壳体时,由于对TC11的特性掌握不透,设计考虑不周,造成了使用过程中刹车壳体卡台断裂的故障。通过分析故障原因,制订了改进措施,经试验试飞验证,改进措施有效,为TC11在航空机轮上的推广应用积累了经验。While TC11 titanium alloy is firstly applied to a certain type aircraft＇s wheel brake shell, fracture failure is caused by the lack of understanding of the new material＇s properties. By analyzing the cause of the problem, improvement measures are taken and verifi ed effectively by ground and flight tests, which contribute to the popularization of TC11＇s application in aviation wheel.
