Abstract

The method of the rotating disk with equitable surface is investigated kinetics of dissolution of Cu, Ti, Zr, crystal and fine-grained modifiers on the basis of systems of Al-Zr, Al-Cu-Ni-Zr in the aluminum alloys brand В95. It is established that the specific rate of dissolution of ligatures approaches the speed of dissolution of pure copper (18,6 kg/(m2·s)) at a temperature of 1023 K and speed of 600 rp/m.
