Abstract

MENDOZA-OLIVEROS, M. E. et al. Study of the stir speed and time in AA6030 matrix reinforced with Al₂O₃ nanoparticles. J. appl. res. technol [online]. 2022, vol.20, n.1, pp.17-23.  Epub May 30, 2022. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2022.20.1.1642.

The effect of speed and time of stirring for AA6063 matrix manufactured by Electric Induction Furnace and reinforced 0.75wt.% and 1.5wt.% of Al2O3 nanoparticles is studied. The specimens produced were subjected to tensile, microhardness, and tribology tests. It is observed that an increase in the speed and agitation time for AA6063 samples reinforced with 0.75%, favors an increase in the grain size, while an opposite effect is observed with the parts produced with 1.5%, where a grain refining effect is favored, affecting the mechanical properties of the reinforced alloy. The data obtained in this work show that the stirring speed and time will depend on the content of reinforcing particles used in the alloy.

Keywords : AA6063 matrix; Al₂O₃ nanoparticles; speed and time of stirring; mechanical properties.
