A further enhancement of the energy absorption in the TRIP matrix composites should be achieved through cooperative deformation mechanisms. For their quantitative description, the interaction between the crystal defects, the phase transitions in the ceramics and the effect of specific interlayers on the adhesion of the steel/ceramic interfaces must be added into the existing deformation model. Adhesion supporting interlayers will be produced by covering zirconia particles with titanium and AB2O4 spinel forming elements like Fe, Mn, Mg, Al or Si, which are soluble in the austenitic TRIP steel. Thus, also the consequences of the resulting concentration gradients in the steel matrix must be clarified.
