Abstract

The effect of homogenization modes on the microstructure and mechanical properties of a strip of high-magnesium aluminum alloy 1590-4 sparingly alloyed with scandium and containing zirconium, hafnium and erbium was studied. For this purpose, the alloy under study was homogenized using single-stage and two-stage modes. After homogenization by both methods, hot and cold rolling followed by annealing were carried out. After completion of annealing, the fine microstructure and mechanical properties of the samples were studied. The structure and phase analysis were studied using transmission electron microscopy. The mechanical properties, namely, the tensile strength and the yield strength, were studied using the uniaxial tension method. The morphology and chemical composition of nanoparticles were studied using transmission microscopy. In addition, scanning microscopy was used for the cast state to study the morphology and chemical composition of large intermetallic particles. It was found that the samples after two-stage homogenization have better mechanical properties than the samples after single-stage homogenizeation due to more abundant precipitation of fine Al3(ScZrHf) particles. In turn, a larger number of particles formed after two-stage homogenization contributes to a more intense interaction of dislocations with them, thereby causing additional strengthening. On the other hand, a larger number of Al3(ScZrHf) particles at the final annealing stage contributes to the inhibition of dislocations and slows down the processes of polygonization and recrystallization, which also leads to an increase in strength properties. Erbium was detected only in the form of large intermetallic particles, which is apparently due to its very low solubility in the aluminum matrix, so it does not participate in the formation of these nanoparticles.
