摘要
提出了一种AZ31镁合金电子背散射衍射(EBSD)试样制备方法,合理的电解工艺参数:直流电源电压为15～20V,电解电流强度为0.1～0.5A,电解温度为-30～-40℃,电解时间为120～200s。试验结果表明,在对AZ31镁合金试样进行EBSD分析菊池带质量和晶粒取向图时,取向标定率可达到95%以上。而采用传统的制样方法,其取向标定率为85%。此外,新的EBSD试样制备方法具有实用且费用低的优点,试验成本仅为传统方法的1%。
A new preparing technology of EBSD samples for AZ31magnesium alloy was put forward.Suitable technological parameters were presented,such as 15～ 20Vdirect voltage,0.1～0.5A electric current,-30～-40℃electrolytic temperature and 120～200s electrolytic time.The results show that orientation indexing ratio of the AZ31magnesium alloy EBSD sample prepared by the new technology is more than 95% by analyzing quality of Kikuchi zone and grain orientation map,while it is only 85%in the samples prepared by traditional method.Besides,the new preparing method of EBSD samples exhibits the advantages of low cost and economical behavior.
