Abstract

In this study, we examined how different stir casting stirring rates affected the mechanical properties of aluminum-copper (Al-Cu) alloys. Al-Cu alloys were cast and developed utilizing an electromechanical stir casting technique with stirring rates ranging from 0-90 revolutions per minute (rpm), and the alloys had Cu compositions of 0–15 wt. % (weight percent). The microstructural evolution was investigated using an advanced optical microscope. When the developed alloy materials were evaluated for microhardness and tensile strength, it was found that the raise in composition of copper and increase in stirring rate led to progressive improvements in microhardness while changes observed with the tensile strength were obviously indeterminate. The mechanisms responsible for the changes seen are also described.
