| 摘 要： | AZ31镁合金挤压棒材在传统正挤压变形过程中易于形成很强的挤压纤维织构。本文利用EBSD技术对AZ31镁合金挤压棒材的挤压组织进行了表征,发现AZ31镁合金挤压棒材在挤压时形成的织构不是均匀的(0002)基面平行于挤压方向的环状纤维织构,而是由(10 10)棱柱面垂直于挤压方向和(11 20)棱柱面垂直于挤压方向的两个不同的纤维织构组分组成的。因此(0002)极图不足以表达该织构的足够信息,必须用沿挤压方向的反极图表示。纤维织构的存在使得挤压样品具有明显的拉伸各向异性。

| Abstract: | AZ31 magnesium alloy was easy to form strong fiber texture during conventional forward extrusion.In this study,a typical extrusion microstructure was characterized by EBSD technique.The result showed the texture of the extruded sample was not a uniform ring fiber texture with all the(0002) basal plane parallel to extrusion direction,but a fiber texture consists of two different texture component with(1010) prismatic plan perpendicular to extrusion direction and(1120) prismatic plane perpendicular to extrusi... |
