Mechanical Characterization of Friction Stir Welded Magnesium Alloy Reinforced with Titanium Carbide Nanofibers

In this study, we focused on a lap joint arrangement made with a vertical machining machine to examine the impacts of adding Titanium Carbide nanofibers (TiCnf) to the weld pool of Grade AZ31 magnesium alloy. During the investigation, we followed ASTM guidelines for measuring tensile strength and yield strength, percentage of elongation, and Vickers hardness strength. The information gathered showed that welds with a peak tensile strength of 452 MPa showed a remarkable rise in TiCnf content of around 1.5 wt%. Additionally, it was revealed that adding more nanofibers considerably increased micro hardness. This improvement led to polished and distortion-free grain structures, especially in the Heat-Affected Zone (HAZ) and Thermo-Mechanically Affected Zone (TMT). The mechanical qualities of the welds were ultimately improved as a result.
