2018-4-12  The Cr2O3 addition marginally affected the phase composition but greatly affected the microstructural changes of the HVTMPs. Increased amounts of Cr2O3 resulted in a decrease in the uniform distribution of the hematite grains and in an increase in the Fe–Cr solid solutions (Fe1.2Cr0.8O3 and Fe0.7Cr1.3O3) embedded in the hematite grains.
