Abstract

A metallic article comprising a matrix of a heat resistant alloy reinforced by fibres of another material of higher tensile strength is made by arranging the fibres in a metal container which is connected to a source of suction and closed by a diaphragm, pre-heating the container which is then immersed in the molten matrix alloy so that the diaphragm melts and infiltration takes place. The fibres may be Mo, Ta, Nb, W, a Mo base alloy containing 0.01-0.04% C, 0.4-0.55% Ti, 0.06-0.09% Zr or ceramic materials such as TiC, SiC, Si3N4 and Al2O3. The metal fibres may also be coated with SiC, TiC, MoSi2 produced by deposition from the vapour of a hydrocarbon and SiCl4 or TiCl4 or from methyl-trichloro-silane which produces SiC. The ceramic fibres may also be coated with Mo, Tu, Zr, MoSi2 or carbides. The infiltrant matrix alloy may be a Ni based alloy containing 16-21% Cr, 5% max. Fe, 1% max. Si, 1% max. Mn, 0.5% max. Cu, 0.2-0.6% Ti, 0.08-0.15% C.
