Effect of Vanadium and Zirconium on the Formation of Metastable Phases in Aluminum and Iron Alloys

Resumo

Microcrystalline alloys of Al–V, Al–Fe, Al–Fe–V, and Al–Fe–Zr systems are prepared via spinning. The alloys are studied by means of physicochemical analysis. The regions of homogeneity in the resulting supersaturated Al-based solid solutions are determined. The stages of the decomposition of supersaturated solid solutions are studied, along with the effect vanadium and zirconium additives have on the structure and phase composition of rapidly quenched Al and Fe alloys and their mechanical properties, including the effect of dispersion hardening.
