Processing of Aluminium-Silicon Alloy with Metal Carbide as Reinforcement through Powder-Based Additive Manufacturing: A Critical Study

Abstract

Powder-based additive manufacturing (PAM) is a potential fabrication approach in advancing state-of-the-art research to produce intricate components with high precision and accuracy in near-net form. In PAM, the raw materials are used in powder form, deposited on the surface layer by layer, and fused to produce the final product. PAM composite fabrication for biomedical implants, aircraft structure panels, and automotive brake rotary components is gaining popularity. In PAM composite fabrication, the aluminium cast alloy is widely preferred as a metal matrix for its unique properties, and different reinforcements are employed in the form of oxides, carbides, and nitrides. However, for enhancing the mechanical properties, the carbide form is predominantly considered. This comprehensive study focuses on contemporary research and reveals the effect of metal carbide’s (MCs) addition to the aluminium matrix processed through various PAM processes, challenges involved, and potential scopes to advance the research.

Investigating Mechanical Properties of Hybrid Polymer Composite Reinforced with S-Glass and Luffa Fibres

“…Outside factors would almost certainly affect the loading of designed structures, and this can be expected to happen during maintenance, assembly, and administration tasks [7,8]. One of the major unknowns in matrix polymer composites is impact resistance.…”

Study on TIG welding parameters for joining different kind of aluminium tube with a tube plate

“…Welding is a continuous connecting procedure that involves fusing metals, alloys, and polymers. To establish a weld a melted pool material that solidifies to provide a robust bond between the components, a filler material is occasionally utilized [1,2]. The steelmaking modifications which take place all through welding, as well as adjustments in stiffness in the weldment led to fast crystallization, the dimensions of combustion caused by materials reacting with atmospheric oxygen, and the propensity for brittle fracture in the joint angle, all have an impact on a molecule's hardenability [3,4].…”
