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.
