室温下,对AZ31镁合金轧制板材依次沿轧向(RD)、横向(TD)和法向(ND)压缩,依据压缩路径的不同,分别对应RD、RD-ND、RD-TD和RD-TD-ND4种压缩方式,分析上述压缩过程镁合金的力学性能和织构变化,并对上述压缩变形后的镁合金分别进行室温沿RD方向拉伸变形,分析不同压缩变形方式对拉伸力学性能的影响。结果表明:RD-TD压缩过程中对应的{1012}-{1012}二次孪晶大幅度提高屈服强度,试样经RD-TD压缩后产生强烈的{1011}锥面织构和{1010}柱面织构。镁合金经RD方向压缩后,在后续的RD方向拉伸变形中{1012}解孪晶的启动明显提高塑性。 |

The rolled AZ31 Magnesium alloy sheet was sequentially compressed along rolling direction (RD), transverse direction (TD) or normal direction (ND) at room temperature, the compressions RD, RD-ND, RD-TD and RD-TD-ND were correspondingly defined according to the difference of compression paths, and the mechanical property and texture evolution were analyzed for former compressions. The magnesium alloy sheets experienced the former compressions were then stretched along RD at room temperature, respectively, and the influence of compression method on the subsequent tensile mechanical properties was analyzed. The results predict that the yielding strength greatly increases during TD compression of RD-TD compression due to activations of {1012} - {1012} secondary twin, and the intensive {1011} pyramidal texture and {1010} prismatic texture form within the magnesium sheet after RD-TD compression. The plasticity of AZ31 magnesium alloy sheet stretched along RD followed by the RD compression is obviously improved due to activation of {1012} detwinning. |
