摘　　要：利用二维X射线衍射仪测试高分子材料和金属材料的晶体取向结构和在不同物理场下物相的演变情况,从而为研究材料结构对性能的影响以及材料性能的定制加工提供实验测试方法。采用自主研发的同步拉伸仪对样品进行拉伸,原位在线研究高分子样品晶区取向结构在应力场下的变化;采用程序控温热台研究金属材料的物相在温度场下的演变过程。The deformation of materials ＇micro-structure is studied by the 2 D X-Ray Diffraction（ XRD）,this way is useful for analyzing the effect of micro-structure on performance in different physical fields,and could provide the test method for order processing. The orientation of polymer crystal could be in-situ studied in force field by using self-made tensile machine,and the phase transformation of alloy could be observed in the temperature field by using heating stage.
