Abstract (en)
[origin: EP0587494A1] Composite material using a magnesium alloy containing zirconium in combination with a carbonaceous reinforcement, and process for its manufacture. According to the invention such a composite material is prepared by infiltrating a reinforcement made of carbon or graphite fibres with a liquid magnesium alloy containing from 0.3 to 1 % by weight of zirconium, at a temperature of 650 to 850 DEG C. Under these conditions a layer of zirconium carbide is formed on the fibres, containing magnesium in solid solution, corresponding, for example, to the formula ZrCxMgy with 0.3<x<1 and 0.02<y<0.12, which causes the fibres to be wetted by the molten magnesium and produces good adhesiveness between the fibres and the matrix, without degrading the mechanical characteristics of the fibres.
