INVESTMENT CASTING EMERGES AS ONE OF THE MOST DESIRABLE ROUTES TO THE MANUFACTURE OF NET SHAPE METAL MATRIX COMPOSITES COMPONENTS. AS CASTABLE COMPOSITES COME OF AGE, SUPERB PARTS EXHIBITING SUPERIOR DIMENSIONAL STABILITY UNDER THERMOMECHANICAL LOADING HAVE BEEN CAST ON A ROUTINE PRODUCTION BASIS. SEVERAL LIMITATIONS DO REMAIN AND HAVE TO BE CLEARLY SHARED WITH POTENTIAL USERS. FURTHER WORK IS UNDERWAY TO EVALUATE CASTABLE COMPOSITES TARGETED FOR HIGHER TEMPERATURE APPLICATIONS. THEY MIGHT DISPLACE TITANIUM PARTS SERVICING UNDER 315 DEGREES C. DEVELOPMENT WORK CONDUCTED ON COMPOSITES OBTAINED BY PREFORM INFILTRATION ADDS NEW CAPABILITIES TO INVESTMENT CASTING. OF PARTICULAR INTEREST ARE ELECTRONIC PACKAGES WITH EXCELLENT THERMOPHYSICAL TRADE-OFFS.
