    摘要:

    研究了冷加工率對(duì)Ti-35鈦合金板材組織性能的影響。結(jié)果表明：Ti-35鈦合金板材隨著冷加工率的增加，拉伸強(qiáng)度增高，塑性下降，這是符合一般規(guī)律的。然而，當(dāng)冷變形率達(dá)80％，塑性仍然保持在16％，證明這是一種高塑性合金，隨著冷變形量增加，晶粒被拉長(zhǎng)。當(dāng)變形率達(dá)60％～80％時(shí)，晶粒呈纖維化，經(jīng)退火后發(fā)生再結(jié)晶，晶粒等軸化，并伴隨著合金塑性的提高。

    Abstract:

    Effect of cold processing on the microstructure and mechanical properties of Ti-35 alloy plate was studied. It was found that the tensile strength increased, while the ductility decreased with the increase of cold deformation strain, which confirms the general principles. However, remaining of the ductility of 16% with cold deformation of 80% proves the high plasticity of the alloy. When deformation rate was between 60%~80%, grains became fiber. Recrystallization occurred after annealing. Grains became equiaxed with the increase of plasticity of the alloy.
