摘要: 研究了热氢处理对Ti600合金组织演变和硬度的影响. 结果表明: 热氢处理后,在Ti600合金中析出具有四方结构的硅化物粒子S3(0.357% H)和六方结构的硅化物粒子S1(0.497% H). 在氢的质量分数为0.357%和0.497%的试样中均发现有面心立方(fcc)的氢化物, 并且随着氢含量的提高氢化物表现出明显细化的趋势.Ti600合金的硬度随着氢含量的提高而提高, 其主要原因是氢化物、硅化物粒子以及晶格缺陷的存在.

Abstract:The influence of thermohydrogen treatment (THT) on microstructural evolution and hardness of Ti600 alloy has been studied. The microstructural evolution of Ti600 alloy after THT have been investigated and analysed by X-ray diffraction (XRD) and transmission electron microscopy (TEM), and the influence of THT on the hardness of Ti600 alloy has been analysed by hardness testing. The microstructural observation reveals that there are two types of silicides precipitate in the Ti6oo alloy after THT, one is tetragonal silicide S3 (0.357 wt.% H), and the other is hexagonal silicide S1 (0.497 wt.%). Hydrides δ (fcc structure) exist in the specimens with 0.357 wt.% and 0.497 wt.% hydrogen, and hydride δ tends to be refined with increasing of hydrogen. The result of hardness testing shows that the hardness of Ti600 alloy increases with increasing of hydrogen. Additionally, the influence mechanisms of THT to the hardness of Ti600 alloy are discussed, and it is considered in this paper that hydride δ, silicide and lattice defects are the major factors leading to the hardness of Ti600 alloy increase with increasing of hydrogen.
