利用电子背散射衍射技术,研究了冷轧后亚稳态奥氏体不锈钢301L的退火织构和晶界特征,分析了不同冷轧退火温度对织构和晶界特征的影响。结果表明,冷轧退火后奥氏体不锈钢301L的织构主要由Copper{112}〈111〉,Brass{110}〈112〉,Goss{110}〈001〉和S{123}〈634〉组成,并且随着退火温度的升高,织构强度逐渐减弱,重位点阵晶界Σ3晶界含量明显增加,其他重位点阵晶界含量没有明显变化。
The grain boundary character distributions,crystallographic textures of metastable austenitic stainless steel 301L during annealing were investigated by using electron back scatter diffraction（EBSD） technique.The effect of annealing temperature on the grain boundary character and texture was analyzed.The result shows that the texture of metastable austenitic stainless steel 301L is mainly composed of Copper {112}111,Brass {110}112,Goss {110}001 and S {123}634 after cold rolled annealing.With the increasing of annealing temperature,the texture intensity of 301L was gradually weakened and the density of Σ3 coincidence grain boundary increased but the density of other coincidence grain boundary had no significant change.
