Formation of Finely Dispersed Structures in Aluminum Alloys with Niobium in the Presence of Scandium

Аннотация

The possibilities of improving the strength characteristics of alloys based on aluminum and niobium are studied. It is established that the use of scandium allows finely dispersed hardening intermetallide phases to be obtained. The maximum effect of dispersion hardening is observed upon annealing an alloy with the composition Al 99.0 at %, Nb 0.7 at %, and Sc 0.3 at % for 54 h at 300°С.
