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 annealing texture and grain boundary characteristics of 301L austenitic stainless steel after cold rolling were studied by electron backscatter diffraction technique. The effects of annealing temperature on texture and grain boundary properties were analyzed. The results show that the texture of austenitic stainless steel 301L after cold rolling is mainly composed of Copper {112} <111>, Brass {110} <112>, Goss {110} <001> and S {123} And as the annealing temperature increases, the texture strength gradually decreases, the content of Σ3 grain boundaries at the repositioned grain boundaries increases obviously, and the grain boundaries of other repositioned spots show no obvious changes.
