Investigation of the Effect of Grain Refinement on the Mechanical Properties of 6082 Aluminium Alloy

In this study, it is aimed to investigate effect of the grain refinement on mechanical properties AA 6082. The micro structure which plays crucial role in determining alloys varied according size, chemical composition and cooling rate. prescription was prepared by range standard (TSE-EN-573). casting experiments were performed 6082 aluminium alloy belongs Al-Mg-Si system with different percentages (AlTi5B1) composition. Heat treatment that homogenization artificial aging applied after extrusion process, respectively. microstructure analysis tests done produced samples order understand structural strength material. experimental results showed using refinements contributed increasing properties. It observed values increased 17% reduction size 69% 0.11% addition AlTi5B1 master alloy.
