Investigation of the deformation resistance of alloy Al-6% Mg alloyed with scandium at hot plastic deformation temperatures
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 4
Abstract
Materials used in transport engineering in addition to high strength characteristics should have a complex of such properties as low density and increased corrosion resistance, as well as the ability to preserve these properties under conditions of continuous operation under loads. To provide these requirements, the chemical composition of aluminum alloys is continuously improved by alloying elements and technological processes for obtaining products from them. One of the most promising alloys is aluminum alloy of the system Al-Mg-Sc. In the paper, an analysis of the values of the relative coefficients of hardening of metal is given using the hardening-softening technique and also the temperature-velocity parameters favorable from the point of view of the energy efficiency of deformation process are determined for the considered values of the deformation degrees. It is assumed that the peculiarities in the change in the hardening coefficients are explained by the data on structural changes in Al-Mg-Sc alloys, in particular due to the formation of reinforcing nanoscale particles Al3Sc and Al3(Sc1-xZrx) and active dynamic recrystallization.
