对吸氢前后的钛钼合金开展了力学性能研究,获得了其微观结构力学性能的检测数据,反映了合金在微观领域内弹性和塑性变形的特征。结果表明:在4.903N试验力下,钛钼合金吸氢前的维氏显微硬度HV_(0.5)平均值为332,吸氢后的HV_(0.5)平均值则为419。钛钼合金吸氢前后的抗压强度均大于1 730 MPa,试验最大负荷为50kN。钛钼合金吸氢前后力学性能发生变化是由其物相变化引起的。 The mechanical properties of titanium-molybdenum alloy before and after hydrogen absorption were studied, and the testing data of the microstructure mechanical properties were obtained, which reflected the characteristics of elastic and plastic deformation in the microscopic field. The results show that the Vickers microhardness (HV_ (0.5)) of Ti-Mo alloy before hydrogenation is 332 and the HV_ (0.5) average value after hydrogen absorption is 419 at 4.903N. The compressive strength of titanium-molybdenum alloy before and after hydrogen absorption is more than 1 730 MPa, the maximum load of the test is 50 kN. Titanium-molybdenum alloy mechanical properties before and after hydrogen change is caused by its phase change.
