Influence of Vanadium and Niobium Carbide Particles on the Mechanical, Microstructural, and Physical Properties of AA6061 Aluminum-Based Mono- and Hybrid Composite Using FSP

The ceramic particle reinforcement process is one of the most utilized techniques to enhance metal surface. current investigation uses vanadium and niobium carbides reinforce AA6061 alloy using friction stir (FSP). mechanical properties are evaluated ultrasound conventional compressive tests; furthermore, microstructure physical carried out show effect single hybrid additives particles on surface composites aluminum alloy. Scanning electron microscopy (SEM) examine presence distribution VC NbC inside composite matrix. examination revealed a good dispersion homogenized particles. results indicated that significantly enhanced properties. play an important role in improving hardening behavior grain refinement by restricting growth during dynamic recrystallization FSP action. composited AA6061/NbC + recorded increase stress, yield hardness 25%, 20%, 50%, respectively, relative base metal, addition 55% decrease coefficient thermal expansion (CTE) was reported. Moreover, affected corrosion rate with reduction 45%.
