Plasma Oscillatory Pressure Sintering of Mo-9Si-8B Alloy with ZrB₂ Addition

Oscillatory pressure sintering is a novel crystal refinement technology. The doping of different concentrations of ZrB₂ under oscillatory sintering technology (9 Hz) is discussed here, focusing on its macroscopic mechanics and oxidation resistance. In particular, doping 2.5 wt% ZrB₂ can effectively increase the hardness of the alloy, slightly increase the fracture toughness of the alloy and have an outstanding effect on the oxidation resistance of the alloy at 1300 °C, achieving the effect of reducing mass loss by 80.3%.
