Dynamic flow stress behavior of a 5 vol.% Mg-PSZ reinforced TRIP matrix composite at ambient temperature and − 40 °C

A composite consisting of a TRIP (Transformation Induced Plasticity) steel matrix with 5 vol.% Mg-PSZ particles (MgO partially stabilized zirconia) as reinforcement and processed by Spark Plasma Sintering (SPS) was tested under compressive load at a strain rate of 200 s− 1 at both − 40 °C and room temperature. Due to the Mg-PSZ reinforcement, the very fine-grained steel and the low temperature, the material exhibited high strength (true...
