Abstract (en)
A method of producing a composite cast article having a metal matrix containing divided dispersible solid material, i.e. divided solid filler, such as reinforcing fibers or particles, wherein a melt of the metal matrix is placed in a die cavity, a preheated preform of a divided solid filler is placed on top of the melt and pressure is exerted on the preform in a direction parallel to the cavity axis for forcing the preform downwardly into the molten metal whereby the molten metal fully infiltrates the the preform filler, and the resultant cast article is solidified by controlling heat flow within the die cavity in such manner that a solidification from advances unidirectionally, along the cavity axis, entirely through the metal-infiltrated preform layer, while the metal ahead of this front within and at least immediately beyond the preform layer remains molten.
