Fabricated through Friction Stir Processing (FSP), the composite benefited from refined microstructure and enhanced properties. The incorporation of Ni-Fe-Ti-Hf-Nb HEA altered the microstructure of the A356 composite, fostering unique phase formation, grain refinement, and improved homogeneity. These changes potentially translated to enhanced mechanical properties, notably hardness and tensile strength. Moreover, the addition of Ni-Fe-Ti-Hf-Nb HEA bolstered the wear resistance of the A356 composite.

This study highlights the fabrication of secondary (2°) recycled ABS filament with reinforcement of burnt incense stick powder waste (ISPW) for acceptable thermo-mechanical properties and 3D printing capabilities.

The differential scanning calorimetry (DSC) analysis outlined that glass transition temperature (Tg) was improved (from 94.97 °C to 105.27 °C) for the prepared composite.
