Mechanical Characterization of Friction-Stir-Welded Aluminum AA7010 Alloy with TiC Nanofiber

Abstract

The effects of introducing TiC nanofibers (TiCnf) to the weld pool of Grade AA7010 were investigated in this study. The joints were made on a vertical machining centre with a lap joint arrangement. ASTM standards were followed while testing the strength of tensile and yield and percent of elongation, and hardness strength. According to the data, welds formed with TiCnf at around 1.0 wt % had a maximum tensile strength of 452 MPa. It was discovered that utilizing many nanofibers also enhance microhardness. Because of the nanofiber, the HAZ and TMT grains were polished and distortion-free, resulting in improved mechanical properties.
