【摘要】 研究了不对称轧制晶粒细化问题,结果表明,与对称轧制相比,在相同的变形量下不对称轧制可以使晶粒更细。另外还分析了不对称轧制时,剧烈变形是由于变形区内产生的附加剪切变形和一般压缩变形共同产生的。更多还原

【Abstract】 Grain refinement during asymmetric rolling was studied.The result showed that the grains of asymmetric rolled product are finer than that of symmetric rolled product in the same reduction.The severe deformation during asymmetric rolling is composed of shear strain and normal reduction strain.更多还原
