摘要
研究了电场时效处理中电场强度对LY12铝合金的微屈服强度和微变形行为的影响,也研究了直流电场时效和脉冲电场时效对合金微变形行为的影响。结果表明,适当的电场时效可以使合金的微屈服强度明显提高,优选出最佳的电场时效工艺参数是:E=2kV/cm,190℃/10h。
The influence of electric field intensity during aging in an electric field on the microyield strength and microplastic deformation behavior of LY12 aluminum alloy was studied Moreover, the microplastic deformation behaviors of the alloy after aging in a direct current electric field and pulse electric field,were studied respectively The results show that the microyield strength of the alloy is obviously improved by an appropriate procedure of aging in an electric field and the optimum processing parameter is E=2kV/cm,190℃/10h
