The Influence of the Addition of MoS 2 Particles on Stir Cast Al-7175/Si 3 N 4 -Based Hybrid Composites Mechanical and Physical Properties
International Journal of Metalcasting(2024)
摘要
In this paper, the mechanical and physical behavior study of hybrid aluminum metal matrix composites has been carried out. Aluminum 7175/Si 3 N 4 -based hybrid composites have been developed by infusing MoS 2 and Si 3 N 4 particles via vacuum-assisted bottom pouring stir casting technique. Mechanical and physical behavioral synthesis was carried out by varying weight percentages of Si 3 N 4 (0–9%) and MoS 2 (3, 5 and 7) particles as reinforcement. Apart from mechanical and physical behavioral evaluations, the microstructural features were investigated. The microstructural analysis showed a grain refinement with the addition of reinforcing content. The hybrid composites results exhibited micro-hardness, tensile strength and compressive strength with 7 wt% of Si 3 N 4 and 5 wt% MoS 2 . The density of HAMMCs was also improved by 2.77% as compared to monolithic base alloy. During the micro-hardness evaluation of cast samples, influence of variation in indentation load and dwell time was examined.
