ABSTRACT:
A method of making a casting reinforced with a reinforcement insert, such as a fiber reinforced metal matrix composite insert or intermetallic insert therein, wherein a preformed fiber reinforced metal matrix composite reinforcement insert is clad or covered with a material that is effective to avoid the aforementioned adverse reactions between the insert/melt and any exposed insert fibers/matrix, the clad insert is suspended in the mold cavity, a melt is introduced into the mold cavity about the clad insert, and the melt is solidified about the clad insert to provide a casting of the solidified melt having the clad insert disposed therein to reinforce the casting.
