METHOD FOR PRODUCING Al-Ti MODIFYING ALLOY

摘要

FIELD: metallurgy.;SUBSTANCE: method comprises interaction of porous lump titanium raw material with overheated aluminium melt, at that titanium sponge and/or briquetted titanium chips are used as porous lump titanium raw material, weight ratio of porous lump titanium material to aluminium is maintained within (0.38÷0.58):1, while level of overheated aluminium melt is maintained above the level of porous lump titanium raw material, at that method of self-propagating high-temperature synthesis is used to produce concentrated titanium-containing aluminium alloy with content of titanium of 27.5-36.7 wt %. Obtained titanium-containing alloy is cooled and ground up to content of fraction of minus 10 mcm not less than 95%, after that ground alloy particles are introduced into aluminium melt with the production of modifying alloy or applied to surface of aluminium wire or a strip with production of modifying ligature.;EFFECT: production of aluminium-titanium alloy with particles of titanium aluminide uniformly distributed in the volume of the alloy.;10 cl, 2 dwg, 2 tbl, 2 ex
