Abstract
New hardmetals with a structural gradient for milling applications are investigated experimentally and numerically on several length scales. On the macroscale, milling tests are performed and a numerial model for up-milling is developed. On the mesoscale, the interaction of cracks with the graded surface zones, especially large soft binder islands are studied. On the microscale, the influence of shape and volume of such inclusions are investigated, further on, crack propagation in realistic microstructures is simulated. On the sub-microscale crack propagation and void growth in the ductile binder are modelled with crystal plasticity.
