One of the most important for the deformed aluminium alloys types of modifying is crushing of a matrix phase is in-process considered. Two methods to introduction of modifier in an alloy are rotined: as ligature together with other constituents of charge and as a continuous serve at casting bullion by ligature bar in crystallizer pan. The primary and second intermetallic, their middle resulted diameter, by volume stake, and also distance between particles primary and second intermetallic are studied. Rotined and grounded expense entered in the alloy of 01570 scandium and zirconium are formed a consolidating phase.

Key words: deformed aluminium alloy, modification, scandium, zirconium, structure of billion, primary and second intermetallic.
