The Strength and Toughness of Cast Aluminum Composites as a Function of Composition, Heat Treatment and Particulate 960162
Net-shape aluminum matrix composite components and test specimens were produced through an advanced pressure infiltration process where molten alloys are infiltrated into ceramic preforms. Test specimens were cast with 4 aluminum alloys with alumina and SiC reinforcements. Specimens were heat treated to T6 and T7 conditions and to a special condition wherein intermetallic particles are precipitated at internal interfaces. Alumina reinforced materials were generally stronger and tougher than silicon carbide reinforced materials. Maximum flexure strengths of 653 and 683 MPa were achieved through alumina reinforced 520 and 295 alloys, respectively. Fracture toughness and Charpy impact values were also determined.
