Abstract
The present work deals with the mechanical behaviour of a commercial AS9U3/SiCp composite formed by sand and permanent mold casting. The corresponding unreinforced matrix was also formed in the same conditions. As cast and heat treated (T6) tensile test specimens were machined and tested at room and 300° temperatures. The results showed a finer microstructure for both materials formed by permanent mold casting, with improved properties for the composite over those obtained for the unreinforced matrix, although this improvement was more clearly shown at 300°. The highest mechanical properties were obtained with the T6 heat treatment for both materials formed by permanent mold casting.
