摘　　要：为了准确检测B82Mn高碳钢盘条奥氏体晶粒度的大小,采用冲击法和电子背散射衍射(EBSD)自动分析技术显示其晶界,并与金相腐蚀法进行了对比。结果表明:与直接侵蚀法相比,冲击法和EBSD分析技术可以更好地显示高碳钢热轧态盘条的奥氏体晶界,干扰因素少,检测结果真实可靠。In order to accurately detect the austenitic grain size of B82 Mn high carbon steel wire rod,ballistic method and electron backscattered diffraction（ EBSD） automation analytical method were used to show the grain boundary,and to compare with metallographic etching method. The results show that compared with the direct etching method,ballistic method and EBSD analytical method can show the grain boundary of the high carbon steel rod better,with less interference factors,and the evaluation results are reliable.
