摘要
基于透射电镜对两种含Si钢下贝氏体亚结构的分析,确定相变非均匀切变元素,建立了塑性协调双切变理论晶体学模型。该模型给出的晶体学理论值与两种试验用钢实验值符合很好。
Based on the TEM analysis of substructures of lower bainite in two
steels containing Si, the lattice invariant shear elements were determined and a plastic
accommodation double-shear model was proposed. The theorotical predictions about
crystallography given by the model are in good agreement with the experimental da-
ta for the steels tested.
