the machinability of two classes of high-temperature composites (sic whisker/2124 aluminum and sic whisker/alo//2o//3) with an abrasive waterjet (awj) was investigated. the as-machined surfaces were characterized by scanning electron miscroscopy (sem), energy dispersive x-ray spectroscopy (eds), and profilometry to determine the surface finish. microhardness measurements were also performed on the as-machined metal matrix composites. awd appears to be promising method due to its fast speed and economical operation. it gives relatively smooth surfaces coupled with minimum subsurface microstructural damage.
