摘要
借助透射电镜和Ｘ射线衍射仪探讨了氢对Ｓｕｐｅｒ－α２合金β固溶后时效组织的影响．结果表明，氢使时效组织显著细化，使析出相呈细小板条状规则排布．此外，氢还促进Ｂ２相转变为Ｏ相．
The effect of hydrogen on the microstructure of supere-α2 alloy with β solution and ageingtreatment has been researched by TEM and XRD. The results show that hydrogen can refine the agedndcrostructure. Fine-lath precipitates are found to be regUlar arrangement in the aged microstructure. In addition, hydrogen can also promote the formation of O phase, which is a product of B2 transformation.
