  3. Abstract:
  4. In this paper, an investigation of bi-material parts produced by a two-component metal injection moulding process is presented. The compatibility of different materials for this process was evaluated by sinter dilatometry, taking into account the effects of powder particle size, powder loading and use of master alloys on the sintering behaviour. In a second step, sample material joints of 316L / H13, 316L / 17-4PH and 316L / iron were moulded, debinded and sintered together. The interfaces obtained were examined by optical microscopy and SEM. The diffusion of alloying elements across the interfaces was shown as a function of sintering temperatures. Changes in microstructures and chemical compositions across the interfaces were investigated. It was found that even with significant differences in chemical composition or sintering behaviour, solid material bonds could be obtained by appropriate tailoring of the materials and manufacturing processes
