METHOD OF OBTAINING LIGATURE OF ALUMINIUM-TITANIUM Russian patent published in 2016 - IPC C22C35/00 C22C1/02

Abstract RU 2599134 C1

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, particularly to preparation of modifying ligatures aluminum-titan, which are used in production of aluminium alloys for crushing structures of cast articles. In the method of milling of particles of titanium aluminide TiAl₃ occurs due to introduction of ligature at its melting in vacuum induction high-frequency furnace at 1,100-1,200°C and rarefaction 0.799-1.066 PA to 0.05 wt% of tantalum nitride nanopowder TaN contained in the volume of the pressed rod consisting of a composition of particles of aluminum and nitride nanopowder tantal TaN, with subsequent casting of ligature into molds without removing vacuum.

EFFECT: invention enables to use ligature for crushing of structures of cast alloys, modifying agent in which are particles of intermetallic compound of titanium aluminide TiAl₃.
