本文研究了TC_6钛合金片状、网篮、等轴和双态组织的振动疲劳性能。
The vibration fatigue characteristics of TC6 titanium alloy with Widmanstatten, basket-weave, equiaxed and duplex microstructures have been studied.
结果表明：该合金等轴组织和双态组织的室温力学性能和疲劳裂纹扩展阻抗差别不大；
The results show that the equiaxed and bi-modal microstructures have the similar mechanical properties and fatigue crack propagation rate.
双态组织的断裂应力随加载速度的上升而增加，微裂纹面密度随加载速度的增加明显下降；
The fracture stress of DP microstructure increased with the increase of displacement speed, and the microcrack density increased with the decrease of displacement speed.
对原始组织为铸态和热轧态的2205双相不锈钢试样进行了不同条件下的固溶处理热模拟试验。
The solution treatments were performed with the specimens of 2205 duplex stainless steel, which possessed different initial microstructures.
