Summary

Molybdenum disilicide (MoSi2) was in situ reinforced with 30 vol% of either TiB2, ZrB2, HfB2, or SiC by the XDTM process. The compressive yield strengths of these composites, along with an unreinforced alloy, were investigated as a function of temperature from room temperature to 1300°C. Although particle type has some effect, the major difference in the high-temperature yield stress among the alloys is related to the reinforcement size and shape.
