摘　　要：本文在主应力法的基础上,考虑变形的不均匀性因素,推导出新的圆柱体坯料超塑性压缩载荷计算公式,与原公式相比,其计算值更接近实值.For computing the superplastic compressive load,a new formula is derived by taking into account the inhomogeneity as a contributing factor of deformation,and based on the method of princi- ple stress.As compared with the original formula,the new formula provides a calculated value even more close to the real velue.

关 键 词：坯料 超塑性 压缩 变形力 不均匀性
