Abstract
A method for shaping a consolidated, substantially oxygen-free, equiaxed MoSi.sub.2 /SiC composite body having an average grain size of 10 .mu.m or less, a SiC content of 2 to 60 v/o and relatively low strength and relatively high ductility comprising subjecting the composite body to plastic deformation under conditions of forming temperature and rate of deformation such that grain growth is substantially avoided, the MoSi.sub.2 /SiC composite body being obtained by providing particles of molybdenum, silicon and carbon in a proportion relative to each other required to produce a composite powder of MoSi.sub.2 and SiC having a composition in that segment of the ternary diagram of FIG. 1 designated A, and subjecting the particles to mechanical alloying under conditions and for a time sufficient to produce the composite powder, followed by consolidation of the composite powder.
