Phase Composition of Mg-PSZ in Manganese Alloyed TRIP-Steel MMC Processed via Steel Casting and Conductive Sintering

Metal matrix composites (MMCs) containing TRIP‐steel/Mg‐PSZ were processed by steel casting and conductive sintering. The MMC was based on austenitic steel in the system Fe–CrMnNi showing transformation induced plasticity (TRIP). Depending on the processing route the different phase composition of...

Description
Summary:Metal matrix composites (MMCs) containing TRIP‐steel/Mg‐PSZ were processed by steel casting and conductive sintering. The MMC was based on austenitic steel in the system Fe–CrMnNi showing transformation induced plasticity (TRIP). Depending on the processing route the different phase composition of MgO partially stabilized zirconia (Mg‐PSZ) was investigated by scanning electron microscopy (SEM), energy dispersive X‐ray microanalysis (EDX) as well as electron backscatter diffraction (EBSD). The interactions between the alloying metals of austenitic stainless steel and the ceramic stabilizer (MgO) during processing lead to a significant change in the phase composition of the Mg‐PSZ.
