Abstract
Machinability of high temperature composites was investigated. Target materials, 15 and 25 vol % SiC whisker-2124 aluminium composites, were machined by electrodischarge sinker machining (EDM) and diamond saw. The machined surfaces of these metal matrix composites were examined by scanning electron microscopy (SEM) and profilometry to determine the surface finish. Microhardness measurements were also performed on the as-machined composites.
