摘要
采用恒载电解充氢的方法和X射线衍射分析方法,研究了Ti1023电子束焊接接头引起氢致开裂氢含量门槛值以及Ti1023合金基体与焊缝中由于相成分的不同造成对氢致开裂的敏感性的差异;同时通过扫描电镜分析了不同充氢状态下试件的断口特征。采用等效人工时效的方法,借助离子探针分析技术,对Ti1023合金电子束焊接接头中氢的动态行为进行了研究。
The electrolytic hydrogen charging with constant current and X-ray diffraction were used to investigate the hydrogen content threshold of the hydrogen induced cracking for Ti1023 titanium alloy EBM joints and the effect of the microstructure phase on sensitivity of hydrogen induced cracking. The scanning electronic microscopy was employed to observe the fracture appearance on different hydrogen charging condition. By means of the artificial aging and ion probe analysis, the dynamic behavior of hydrogen in Ti1023 titanium alloy EBM joints was also studied in this paper.
