由于中子衍射织构分析的高质量和统计数据，详细描述了六种镁合金（AM 20-AZ 31-AZ 61-AZ 91-ZC 71-WE 43）的晶体织构变化。ZC 71的晶体学织构基本上都是由{0001}< 10-10 >、{10-10}等理想织构组分< 11-20 >和< 0001 >//ND、< 10-10 >//ED等纤维织构组分组成的，织构组分的存在和织构的锐度与合金元素Al的含量有关，ZC 71的特殊性在于只有一个主要织构组分{10-10}< 11-20 >。WE 43在基底极图中显示了中心极的分裂，但纹理成分与其他合金相同，没有倾斜。
Due to the high quality and statistics utilizing neutron diffraction for texture analyses, the crystallographic texture variation of six Mg-alloys is described in detail (AM20-AZ31-AZ61-AZ91-ZC71-WE43). More or less in all cases, the crystallographic texture is composed of some ideal texture components such as {0001} < 10-10 > and {10-10} < 11-20 > and fiber components such as < 0001 >//ND and < 10-10 >//ED. There is a dependency of the existence and texture sharpness of texture components with alloying elements such as the amount of Al. ZC71 is special with one dominating texture component {10-10} < 11-20 >. WE43 shows the split of the central pole in the basal pole figure but texture components are identical to other alloys without the tilt.
