ABSTRACT
Porous materials have received extensive attention for energy absorption
in the last few years. In terms of this study, austenitic
TRIP-steel/Mg-PSZ-composite honeycomb structures are formed with
different mixing proportions due to ceramic extrusion at room
temperature. Their specific energy absorption (SEA) as well as their
compression strength have been registered as a function of the
compressive strain. X-ray diffractometry (XRD), electron backscatter
diffraction (EBSD) as well as electron dispersive X-ray (EDX) analysis
support the microstructure characterization. The zirconia addition has
mainly contributed as a hard phase in a ductile TRIP steel matrix and
has reinforced the composite material up to a compressive strain of
about 24%.
