Abstract
In recent years, aluminium and its hybrid composites receiving more attention due to its excellent property combinations like improved mechanical properties, better wear and high corrosion resistance, ease to process and probably reduced production cost etc.. Composite is made of two phases one is matrix and another one is reinforcement. The performance of composite highly depends on some key factors that decide overall performance and they are properties of constituent phases, reinforcement size, reinforcement distribution in the matrix and their interfacial interaction. Particle reinforced metal matrix composites (particulate metal matrix composites- PMMCs) are becoming more popular due to their low cost, easy to process and compatible to conventional processing techniques. Also they give isotropic properties. The most commonly used reinforcements are carbides, oxides and nitrides. A lot of research has taken place including carbide and oxide as a reinforcement particles for aluminum matrix composites (AMCs) and hybrid aluminium matrix composites (HAMCs) while there is a bit research lag in use of nitride as a reinforcement for development of AMCs and HAMCs. Recent competitive market demands the material having better combination of properties, cost effectiveness and eco-friendly nature. Present article focused on to study the microstructural features, physical properties, mechanical and tribological behavior of aluminium matrix composites when reinforced with silicon nitride particles (Si3N4). Potential area of applications has also been suggested on the basis of literature data. In this review a comprehensive study has done for current scientific development carried out in Al based Si3N4 composites as well as its future scope has also been discussed.
Highlights
Metal matrix composites (MMCs) are growing continuously
The present article is focused on to review the outcome when Si3N4 is used as a reinforcement to develop the Aluminum metal matrix composites (AMMCs), what is its feasibility with aluminium matrix and property enhancement after its introduction etc
It is found from the literature the Silicon nitride (Si3N4) has excellent mechanical and wear properties along with high thermal shock resistance, good thermal conductivity as a reinforcement it is feasible to use for fabricating AMMCs [31]
Summary
Silicon Nitride as a Reinforcement for Aluminium Metal Matrix Composites to Enhance Microstructural, Mechanical and Tribological Behavior and to achieve uniform dispersion in melt mechanical stirrer is used. It is inexpensive, simple, flexible and applicable for mass production which make it advantageous [27]. The present article is focused on to review the outcome when Si3N4 is used as a reinforcement to develop the AMMCs, what is its feasibility with aluminium matrix and property enhancement after its introduction etc It is found from the literature the Silicon nitride (Si3N4) has excellent mechanical and wear properties along with high thermal shock resistance, good thermal conductivity as a reinforcement it is feasible to use for fabricating AMMCs [31]. This review will comprehensively cover physical, mechanical, microstructural and tribological properties of AA/Si3N4 composites and lights on its future perspectives
