摘要

Mechanical properties at cryogenic and ambient temperatures were examined for two alloys belonging to Al-Mg-Sc-Zr system and containing 4.5 and 6 wt% of Mg. It was shown that both aluminum alloys exhibits negative temperature dependencies of elongation-to-failure, yield stress (YS) and ultimate tensile strength (UTS) in the temperature interval 77-293 K. In rolled condition, the Al-6%Mg-0.2%Sc-0.09Zr alloy exhibits slightly higher strength in comparison with the Al-4.5%Mg-0.2%Sc-0.09Zr alloy; ductility of these two alloys is essentially the same in whole temperature interval.
