Investigate the impact of preheating heat treatment on diffusion welding of ۲۰۲۴ Aluminum

The present research investigated the impact of the diffusion welding process and preheat-treatment on mechanical properties. using T۶ temperature for heat treatment, then diffusion welding was accomplished. Mechanical properties were studied by tensile strength test. The results showed that per-heating sample at T۶ in the diffusion welding process declined the tensile strength. Also, in this process by using a lower temperature range compared to liquid state methods eliminates shrinkage defects and results in moreexcellent stability and improved physical properties of ۲۰۲۴ aluminum.
