利用X射线衍射技术研究了ZK 60镁合金挤压态在不同拉伸应变下的织构演变。随着应变的增加，大部分晶粒的{0002}基面逐渐向拉伸方向倾斜，TD试样的这种趋势更为明显。这有力地表明，艾德和TD样品之间的力学各向异性和变形模式的差异不仅是由初始的基底织构引起的，而且是由拉伸试验过程中发展的织构引起的。
The texture evolution of an as-extruded ZK60 Mg alloy with different tensile strains has been determined by X-ray diffraction technique. As strain increases, {0002} basal plane of most grains gradually inclines to the tensile direction, which is more pronounced for TD sample. This firmly suggests that the mechanical anisotropy and the difference of deformation modes between ED and TD samples are not only caused by initial basal texture, but also by the developed texture during the tensile test.
