等径角轧制ZK60镁合金板材的组织与性能 程永奇1,傅定发1,李志华1,吴有伍1,夏伟军1 (1.湖南大学材料科学与工程学院,湖南,长沙,410082) 摘要:对采用等径角轧制工艺(ECAR)制备的ZK60镁合金板材研究发现,与直接轧制的板材相比,等径角轧制板材的晶粒取向由(0002)基面取向演化为非基面取向,经等径角轧制后,板材晶粒没有得到细化,同时形成了大量的平行排列的细密孪晶,强度明显提高.与1个道次直接轧制的板材相比,1个道次等径角轧制的板材其抗拉强度由271.7 MPa增大到328.3 MPa,但伸长率由25.5%降低至8.5%. 关键词:等径角轧制; ZK60镁合金板材; 晶粒取向; [全文内容正在添加中] ......
