Abstract
A method of making a functionally graded metal matrix composite (MMC) sheet having a central layer of particulate matter, the particulate matter having a size of at least about 30 microns. The method includes providing a molten metal containing particulate matter to a pair of advancing casting surfaces. Solidifying the molten metal while advancing the molten metal between the advancing casting surfaces to form a first solid outer layer, a second solid outer layer, and a semi-solid central layer having a higher concentration of particulate matter than either of the outer layers. Solidifying the central layer to form a solid metal product including a central layer sandwiched between the outer layers and withdrawing the metal product from between the casting surfaces.
