Simulation of Aluminum Alloy Temperature Utilizing MATLAB Programming Language for Annealing, Soaking, Microstructure Uniformity, and Quenching Treatment Processes
This abstract presents a study in which the temperature behavior of aluminum alloy is simulated using MATLAB programming language, focusing on annealing, soaking, achieving microstructural uniformity, and quenching treatment processes. The investigation involves aluminum alloy 6061 in various forms, such as plates, cylinders, rectangles, cubes, and spheres, specifically in the states of 6061-O, T1, T4, and T6. The simulation encompasses crucial parameters like geometry, thermal conductivity, density, and load patterns, which dictate the potential for effective heat treatment. The Finite Difference Method is employed to analyze the temperature changes in the treated specimens.
The results of the simulation indicate that annealing at a temperature of 409.5°C leads to fracture resistance of 670.5 MPa and an ultimate tensile strength of 298 MPa, along with 4% ductility. Maintaining the temperature of 409.5°C for approximately 600 seconds is essential for achieving a uniformly distributed microstructure, followed by quenching in water for 799 seconds to reach a room temperature of 28°C. This process imparts an equivalent treated thickness of 25mm in the plate section. The study reveals that as the annealing temperature increases, the strength of the workpiece also increases, accompanied by higher thermal conductivity. Notably, heat treatment on the plate surface is more rapid compared to the rectangular and cylindrical surfaces of the aluminum (6061-O). The calculated heat transfer coefficients are 1384 W/m²K for the plate and 692 W/m²K for the cylindrical specimen, both at a Biot number of 0.2.
The heat treatment procedure concludes after 2256 seconds, demonstrating that aluminum 6061-O is more amenable to heat treatment than aluminum 6061 in states T1, T4, and T6 under the same conditions. However, annealing of aluminum 6061 nullifies the effects of cold working, resulting in a strain of 0.002, a yield strength of 149 MPa, and 0.2% ductility.
