Abstract

1354366 Sintered forming tool MANNESMANN A G 16 June 1971 [29 June 1970] 28089/71 Heading C7D A forming tool comprises a sintered porous refractory metal alloy with a pore volume < 50% the surface pores being filled to a depth of 5-10 mm. with a solid, non-metallic inorganic material which is non-deformable below 650‹C. The remainder of the tool has a density at least 90% theoretical. The porous tool is formed by compacting and preferably sintering alloy powder, granules, chips or fibres. That part not to be impregnated is consolidated to at least 90% density prior to the impregnation. The powders are steels, alloys containing at least 40% Ni or alloys containing at least 22% Co. Impregnation or infiltration is effected during sintering or as a separate step. The impregnant may be of the required composition e.g. water glass, glasses, or enamels, chlorides or aluminates; or a metal or alloy such as Al, Mg, Al-Si, Al-Ti may be used and then converted to the oxide, carbide or nitride by reaction with O 2 , C or N 2 which may be present in the porous body or supplied in the heat treating atmosphere.
