本文通过对 Ti-6Al-4V(modi.)和 Ti-4A1-4Mo-2Sn-0.5Si(IMI550)等α-β钛合金的超塑性(SP)研究,讨论了两相钛合金超塑性变形(SPD)的数学描述和超塑性变形机理。研究 SPD 过程中σ和ε的关系,采用应变速率循环法(Strain rate cycling)。一般进
In this paper, the superplasticity (SP) of α-β titanium alloys such as Ti-6Al-4V (modi.) And Ti-4A1-4Mo-2Sn-0.5Si (IMI550) SPD) mathematical description and superplastic deformation mechanism. The relationship between σ and ε in the SPD process was studied using a Strain rate cycling method. General into
