研究了塑性变形不均匀性对Ti 15 3合金冷强力旋压可旋性和成形质量的影响。结果表明强力旋压时由于局部加载引起金属塑性变形不均匀 ,从而导致裂纹产生和内外表面晶粒尺寸的不均匀性。为避免冷强旋时产生裂纹 ,第 1道次的减薄率取 30 %～ 40 %为宜 ;为避免组织不均匀性 ,总的减薄率要达到 6 0 %以上 The effect of plastic deformation inhomogeneity on the cold spinning force and forming quality of Ti 15 3 alloy was studied. The results show that due to local loading, the plastic deformation caused by partial loading is not uniform during the intensive spinning, which leads to the generation of cracks and the nonuniformity of grain size on the inner and outer surfaces. In order to avoid cracks when cold and strong, the first pass of the thinning rate of 30% to 40% is appropriate; in order to avoid the unevenness of the organization, the total thinning rate to reach 60% or more
