Abstract (en)

[origin: EP0408257A2] A metal matrix composite material having uniformly dispersed intermetallic compounds and no micropores is manufactured by forming a porous preform (18) including 60% to 80% by volume fine fragments essentially made of aluminum, 1% to 10% by volume fine fragments essentially made of nickel, copper or both, and 1% to 10% by volume fine fragments essentially made of titanium so that these fine fragments occupy in total 62% to 95% by volume of said preform (18), and at least a part of the preform is contacted with a melt (22) of a matrix metal selected from aluminum, aluminum alloy, magnesium and magnesium alloy, so that the porous preform is infiltrated with the melt under no substantial application of pressure to the melt.
