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.

由制造过程产生的材料变化将通过衍射方法进行研究，以建立过程特征。通过X射线衍射仪中的拉伸试验机，将分析热机械载荷下的表面层行为和稳定性。将继续进行深轧过程中同步加速器辐射的现场实验，并将其扩展到磨削过程。利用该设备，可以在加载期间和加载后获得有关（残余）应力和微观结构变化的原位时间和空间分辨信息。最终将开发出一种使用新型 Cos-α 衍射仪进行快速残余应力测量的方法。
