The present paper deals with the development of metal matrix composites with improved mechanical properties based on metastable austenitic TRIP‐steel and magnesia partially stabilised zirconia. The ceramic material is characterised regarding the influence of different additives (MgAl 2 O 4 , MgO, Al 2 O 3 ) on the monoclinic/tetragonal/cubic phase composition. First results for the infiltration of ceramic preforms are shown, on the one hand performed by conventional steel casting technology and on the other hand by submerging of preforms in a metal melt using a steel casting simulator.
