Normal Temperature Mechanical Properties of 6082 Aluminium Alloy as a Function of Tempering Temperature: Experimental and Numerical Approach

Abstract

Our study involved a combination of practical experiments and numerical simulations using the Abaqus computational software. The main aim was to enhance our understanding of the mechanical characteristics exhibited by 6082 aluminium alloy when exposed to tensile forces. To achieve this, we produced 18 samples of standardized dimensions utilizing a parallel lathe. These samples then underwent a thermal treatment comprising a solution treatment, water quenching and various tempering procedures at different temperatures (280̊C, 240̊C, 200̊C, 160̊C and 120̊C), resulting in a range of hardness levels. To obtain the experimental results, we conducted tensile tests on a specialized machine, which were subsequently supplemented with numerical analyses. By adopting this approach, we gained valuable insights into the behaviour of aluminium alloy 6082, specifically regarding its mechanical properties such as hardness, tensile strength, elongation and necking coefficient. This newfound knowledge holds potential significance in the realm of designing and optimizing aluminium structures that operate within high-temperature environments.
