摘要

通过TC11钛合金3D激光快速成形件力学性能实验,获得了静拉伸、S-N曲线、DFR值和断裂韧性等性能数据,并与工程应用广泛的TC18锻件和TC21锻件性能数据进行了对比分析。结果表明:TC11激光成形钛合金的综合性能基本介于TC18和TC21之间;试样存在的未熔合或气泡等内部缺陷对疲劳性能影响较大,后续需持续完善激光成形件的制造工艺,减少内部缺陷,达到内部缺陷的可检可控,确保飞机安全。

Abstract

Through the experiments on mechanical properties of TC11 titanium alloy by 3D laser rapid prototyping,obtained the performance data of static tension,S-N curve,DFR value,and fracture toughness. Furthermore,compared and analyzed the TC18 and TC21 performance data. The results show that the comprehensive properties of TC11 laser forming titanium alloy are basically between TC21 and TC18. The defects of the internal defects such as non fusion or air bubble have great influence on the fatigue properties,and the follow-up needs to continue to improve the manufacturing process and reduce the internal defects,which can be controlled and ensure the safety of aircraft.
