Abstract

The paper presents the results of calculating phase transformations in Al–Zr–Fe–Si alloys. It is urgent to develop a fundamentally new class of aluminum alloys in which the required level of hardening would be ensured by means of alloying them with transition elements and dispersion hardening during heterogeneous annealing, eliminating the hardening operation during their heat treatment. In this case, it becomes possible to maintain the obtained structure stability and high heat resistance at elevated temperatures.
