Abstract
The goal of this study was to investigate the changing characteristics of Heat-Treated Aluminum Alloy 6101 quenched in various media. The research methodology of this research includes performing heat treatment on the Aluminum Alloy 6101 samples at various temperatures, specifically 250℃, 350℃ and 450℃ as well as carrying out quenching processes of the samples using Brine and Water as the main quenchants, and then allowing some samples to cool in the furnace and the rest to be normalized in air, after which mechanical tests (hardness and impact test) will then be carried out on the samples, followed by the microstructural analysis of the alloy. The study concluded that Aluminum Alloy 6101 should be heated to 250°C to achieve the greatest positive effect on its hardness properties, and the air was found to be the best cooling medium. It was also established that Brine Solution used as a quenching media has no significant effect on the hardness property of Aluminum Alloy 6101. Furthermore, the findings revealed that 350°C is the best temperature for increasing the Impact Absorbed Energy (IE) and Impact Strength (IS) of Aluminum Alloy 6101, and that cooling in the furnace also increases the IE and IS.

The findings revealed that 350°C is the best temperature for increasing the Impact Absorbed Energy (IE) and Impact Strength (IS) of Aluminum Alloy 6101, and that cooling in the furnace increases the IE and IS
The graph has revealed that Brine (B) used as a quenching medium for Aluminum Alloy 6101 (AA6101), has no significant effect on the hardness property of the AA6101 specimens, as it only increased the Brinell Hardness Number (BHN) from 39 to 40 (0.39%)
Summary
A silvery-white metal is the 13th element in the periodic table. It is the most common metal on the surface of the Earth, and it accounts for 8% of the central mass of Earth. Aluminum is the 3rd most common chemical element on Earth, after oxygen and silicon. An aluminum alloy constitutes a mixture of metallic and metalloid elements, for example, silicon, tin, manganese, copper, and magnesium can combine with pure aluminum to improve its properties, most notably its strength. Aluminum can gain a lot of strength with the right combination of elements. The alloys of aluminum are classified into many categories;Depending on their material properties, such as; its tendency to react to thermal and mechanical treatment.
