摘　　要：研究了Ti14钛合金半固态条件下的变形行为。半固态变形后,由于液相的出现,加快了原子扩散的能力,其变形激活能明显高于钛合金固态变形时的激活能。结果表明,变形后,晶界、晶内液相长大,形成了宽化的晶界和网格状结构。The deformation behavior of the alloy Ti14 in the semi-solid state has been studied. The results show that the liquid phase enhances the diffusivity of the constituents. The semi-solid deformation energy is more than that of solid deformation. When the Ti14 alloy is semi-solid deformed, the liquid Ti2Cu phase within grains and grain boundaries grows, thereby forming broadened grain boundaries and network structures.
