Analysis of material modifications with diffraction methods ((3) C01)

将通过衍射方法研究制造工艺产生的材料修改，以建立工艺特征。通过X射线衍射仪中的拉伸试验机，分析热机械载荷下的表面层行为和稳定性。将继续在深轧过程中进行同步辐射原位实验，并将其扩展到磨削过程。有了这个设备，在现场的时间和空间分辨的信息（残余）应力和微观结构的变化将获得在加载过程中和加载后。最后提出了一种利用新型Cos- α衍射仪快速测量残余应力的方法。

Material modifications, generated by manufacturing processes, will be investigated by diffraction methods, to set up process signatures. Through a tensile testing machine in a X ray diffractometer, the surface layer behavior and stability under thermo-mechanical loading will be analyzed. In-situ experiments with synchrotron radiation during deep rolling will be continued and extended to the grinding process. With this equipment, in situ time and space-resolved information about (residual) stresses and microstructural changes will be obtained during and after loading. Finally a method for fast residual stress measurement with a novel Cos- α diffractometer will be developed.
