Summary

Molybdenum disilicide - based materials are potential high temperature structural materials, but lack room temperature fracture toughness and high temperature creep resistance. Mullite has intrinsic creep resistance, and may provide extrinsic toughening in whisker form. Composites of molybdenum disilicide reinforced with mullite whiskers have been made by a powder processing route. Ambient and elevated temperaure mechanical property predictions and measurements have been made, and correlated with the microstructure of the composites observed by scanning and transmission electron microscopy.
