| 摘 要： | 在相同的酸洗条件下,研究了不同的酸洗量对钛合金铸件成分、性能及焊接工艺性能的影响。结果表明,随着酸洗量增加,铸件表面脆性α层厚度减小直至完全去除。随着表面脆性α层厚度的降低,铸件焊接性能得到明显提升,吸氢情况有所增加。酸洗过程中产生氢含量增加的情况经热等静压能够得到有效的消除,整个工艺流程对钛合金试样的拉伸性能无明显影响。

| Abstract: | Under the same pickling condition, the effects of pickling amount on the composition, properties and welding performance of titanium alloy castings were studied. The results show that with the increase of pickling amount, the thickness of brittle layer on the casting surface decrease until it is completely removed. With the decrease of the thickness of the surface brittleness layer, the welding performance of the casting is improved obviously, and the hydrogen absorption is increased. The increase of hydrogen content in the pickling process can be effectively eliminated by thermal isostatic pressure, and the whole process has no obvious influence on the tensile properties of titanium alloy samples. |
