Аннотация
Experimental data on the preparation of test master alloys Al–Sc–(Zr, Ti, Y), Al–Zr–(Ti, Y), and Al–Ti–Y, which contain two transition metals and are characterized by the formation of aluminides with the L12 cubic lattice (which is identical to the crystal lattice of an aluminum-alloy matrix), are presented. The growth forms of aluminides in alloys of various compositions are demonstrated. Using Al–4% Cu model alloys (experiments were carried out with 15 and 200 g samples cooled at different cooling rates), the modifying ability of the test ternary master alloys and industrial binary master alloys (used for comparison) has been estimated. Synergetic effects of two transition metals, which consist in grain refining in Al–4% Cu alloys, and a substantial difference in the modifying effects of the binary and ternary master alloys have been shown.
