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 arrang
