奥氏体不锈钢晶粒度测定方法对比
Comparison of grain size determination methods of austenitic stainless steel
摘要
Abstract
Austenitic stainless steels with different grain sizes were electrolytically corroded by oxalic acid aqueous solution with a volume fraction of 10%and nitric acid aqueous solution with a volume fraction of 60%,and samples with twin and without twins were obtained.The grain size was rated by comparison method and cut-off point method,respectively.The results show that when there were twins,the results of the comparison method of coarse-grained samples were coarser than those of the cut-off point method,and the results of the cut-off point method were more accurate.The results of the comparison method of fine-grained samples were close to those of the cut-off point method,but both were finer.When there was no twin,the results of coarse grain sample comparison method were also coarser than those of cut-off point method.Because there was no twin effect in fine grained samples,the results of comparison method and cut-off point method were more accurate.关键词
