Influence of the refractory-components’ concentration decreasing in the miscibility gap on the dispersion of inclusions in the structure of ‘frozen microemulsion’ of metal flakes obtained by high-speed melt cooling is investigated by the example of the monotectic BiZn system alloy. As determined, the refractory components’ concentration decreasing leads to an increase of the inclusions’ dispersion, maintaining the density of their distribution in the structure of samples, and reducing the size range of dispersed-phase inclusions. The conditions for achieving 100% content of ultradispersed inclusions and a high density of their distribution in the structure of flakes are ascertained.

Key words: dispersion-hardened alloys, miscibility gap, ‘frozen microemulsion’, high-speed cooling, ultradispersed inclusions.
