摘要
利用Ｘ射线定量相分析方法，研究加氢热化学处理对Ｓｕｐｅｒ－α２合金显微组织的影响。结果表明，合金组织由α２相，Ｂ２相以及Ｏ相组成，加氢处理可以有效地促进合金中Ｏ相的形成，且随合金中氢含量的增加，组织中Ｏ相的体积分数明显增大。针对加氢热化学处理对Ｓｕｐｅｒ－α２合金组织的影响机制进行了讨论。
Quantitative study of the thermochemical processing(TCP) with hydrogen on the microstructure of Super-α2 alloy has been carried out by means of quantitative phase analysis of X-ray diffraction. The results showed that the microstructure consists of α2, B2 and O phases and the formation of O phase can be effectively promoted by TCP with hydrogen. The volume fraction of O phase in the alloy was found to be increased with hydrogen content. Discussion on mechanism of the effect of TCP with hydrogen on microstructure of Super-α2 was also presented.
