Abstract
A method of producing a metal article having a porous skeleton of compacted ferrous particles infiltrated with a cuprous infiltrant and containing less than 0.25 per cent of carbon, comprises heating the ferrous skeleton and cuprous infiltrant at a temperature between approximately 1,100 DEG C and 1,250 DEG C to melt the infiltrant and fill the pores of the skeleton therewith, maintaining the resulting body at a temperature above the melting point of the infiltrant and below that of the skeleton for approximately 1-6 hours to cause diffusion between the infiltrant and skeleton and penetration of the ferrous particles substantially completely by constituents of the infiltrant, cooling at a rate to soften the body for further shaping and reheating to cause diffused infiltrant to precipitate and thereby to strengthen the body. The body may then be solution treated at or above about 840 DEG C and precipitation hardened at 300 DEG -600 DEG C. The ferrous powder used to form the matrix may contain alloying constituents such as Cr, Mn, W. Ta, V, Ti, Si, Al, Cu, Ni and/or Co. The cuprous infiltrant may have the composition Cu 90 per cent, Fe 2 per cent, Mn 8 per cent. The production of parts for jet-propulsion turbines is referred to.
