Influence of material and interface properties on the transformation behaviour of particle reinforced TRIP-matrix composites

TRIP-matrix composites consist of austenitic steel and a partially-stabilised zirconia, which yields a composite that can undergo a martensitic phase transformation in both components. Numerical analysis of the deformation and transformation behaviour of such a composite is carried out by means of unit cell studies. Both the effect of the yielding behaviour and the transformation kinetics of the matrix material and the effect of the interface characteristics are examined.
