Abstract

Failure tolerant metal matrix composites (MMCs) can be created by combining ceramics with ductile metals. In the frame of the present work open cell foam structures were produced. They contain 95 vol% TRIP-steel (transformation induced plasticity) and 5 vol% zirconia. The goal was to show the effect of transformation toughening within the zirconia particles embedded in the steel matrix during compressive deformation. Deformation induced phase transformation could be shown by using electron backscatter diffraction (EBSD) in combination with energy dispersive X-ray spectroscopy (EDX).
