Notes:
Diamond-cobalt composites are used for cutting tools. Residual stress after manufacturecan reduce the lifetime of such composite cutting tools and, hence, the stress state needs to be wellunderstood. Within this study, stress measurements on a cobalt diamond composite were made bySXRD to deduce stress states in the cobalt matrix using the (222) reflection. The application ofdifferent apertures allowed the investigation of stress in small areas of cobalt surrounding adiamond and in areas at different distances to a diamond. In the areas adjacent to the diamondincreased residual stresses were found in the cobalt matrix. Furthermore, approximations for radialand tangential residual stresses have been derived which show to be different
