Abstract
A method for friction stir forming a metal matrix composite (MMC) structure (76). The method includes the step of providing a substrate (12) comprising a metallic material and securing a preformed MMC layer (14, 16) comprising an MMC material in a position overlying at least a portion of the substrate (12). The method further includes the step of friction stirring the preformed MMC layer (14, 16) with a friction stirring tool (50) which includes a rotating probe (56), including locating the probe (56) at a stirring depth at which the probe (56) extends through the preformed MMC layer (14, 16) into a portion of the substrate (12) and passing the tool (50) through the preformed MMC layer (14) at the stirring depth to friction stir the preformed MMC layer (14, 16) and integrate the preformed MMC layer (14, 16) with the substrate (12).
