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

由制造过程产生的材料修改将通过衍射法进行调查，以建立过程签名。通过X射线衍射仪中的拉伸试验机，分析了在热机械载荷作用下的表面层行为和稳定性。深轧过程中同步辐射的现场实验将继续进行，并将扩展到磨削过程。利用该设备，可以在加载过程中和加载后获得关于(残余)应力和微观结构变化的现场时间和空间分辨信息。最后，开发了一种利用新型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.
