研究两种换向位置对交叉轧钼板织构和性能的影响，即热轧后换向和温轧后换向，取两种轧制方式的纯钼板，检测其拉伸性能（分别沿着轧制方向垂直于轧制方向的横向切割拉伸条，表征轧制方向和横向的拉伸性能，观察是否有区别），并用XRD检测方法探究这两种轧制方式钼板织构的组分和含量，探究力学性能和轧制方式 以及压下量的关系。

Study the influence of two reversing positions on the texture and performance of cross-rolled molybdenum plates, namely, reversing after hot rolling and reversing after warm rolling. Take pure molybdenum plates with two rolling methods and test their tensile properties (respectively along Cut the stretch bar with the rolling direction perpendicular to the rolling direction to characterize the tensile properties of the rolling direction and the transverse direction, and observe whether there is a difference), and use the XRD detection method to explore the composition of the molybdenum plate texture of the two rolling methods. Component and content, explore the relationship between mechanical properties, rolling method and reduction.
