AZ31镁合金板材室温拉深破裂行为 程永奇1,夏伟军2,陈振华2 (1.广东工业大学材料与能源学院,广东,广州,510006;2.湖南大学材料科学与工程学院,湖南,长沙,410082) 摘要:为了探索提高AZ31镁合金板材室温冲压性能的途径,通过断口形貌分析,对板材室温拉深变形过程中的破裂机理进行了研究.结果表明,室温下,对于普通轧制板材,在拉深比达到1.2后即在冲头肩部发生破裂;对于等径角轧制板材.其拉深比可达1.6以上;当拉深比达到1.8时,在杯形件凸缘发生破裂,断面光滑平整.为解理断裂.这主要与板材在拉深变形中的应力应变状态和其非基面织构有关.单向拉伸与断口分析表明其冲压性能和破裂行为的差异,主要是因为这两种板材织构不同所致. 关键词:AZ31镁合金板材; 拉深; 断裂机理; 普通轧制; 等径角轧制; AZ31 magnesium alloy sheet; deep......
