Abstract : The present invention relates in general to articles reinforced with discontinuous composites and the like, and a process of making the same, and in particular, to the use of preforms which can be used to form articles such as microstructurally toughened tubes by casting. Discontinuous metal matrix composites (MMC) have relatively recently been used industrially. The most widely used discontinuous composites are silicon carbide whiskers (SiC) and silicon carbide particles (SiCp) or (SiCw). Discontinuously reinforced aluminum is commonly designated as SiC/Al and SiCp/Al, respectively. Patent applications.
