Abstract Scope |
In the presented work, the effect of heat treatment on the values of the electrical resistivity and the potential level of hardening due to the formation of secondary precipitates of phases of the L12 type of alloys Al-Zr-Sc system for foundry ingots and cold rolled sheets was investigated. By use of the calculated and experimental method carried out quantitative analysis of zirconium and scandium redistribution between the aluminum solid solution and a secondary discharge type L12 after different heat treatment regimes. The positive role of scandium in a more rapid decrease in the values of resistivity in the Al-Zr-Sc system after heat treatment is shown. |
