“…Recently, more authors have extended their research to other particles or alternative reinforcement methodologies. Frequently these include multi-sized reinforcement [144][145][146], in which two different magnitude-sized particles of the same compound are incorporated, or hybrid reinforcement [146][147][148][149][150][151], in which two chemically distinct particles are introduced.…”

Ongoing industrial demand for lightweight materials has spiked the research interest in aluminium-based metal matrix composites for its specific properties. The amount of scientific publication available on the matter has led to the vast production of knowledge, which highlights the need for a systematic assessment if further progress is expected. In this paper, a systematic review of the published literature is conducted, according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, on the Scopus and Web of Science databases were used in the literature search, which was completed on the 29 August 2020. The data of the research work is structured in the particle pre-processing stage and the melt processing stage. The present review clarifies the combined pair-wise effect of particles and the melt treatment performed on their wettability or dispersive or de-agglomerative capability, which allows to achieve their final mechanical properties.

“…The temperature value is determined with a K-type thermocouple for sensing the temperature during the melting process until the desired temperature is attained on the indicator. The SiCp powder is preheated to 1100 °C for 2 hrs in order to initiate surface oxidation before incorporating into the aluminium melt [8].…”

The aim of this study is to investigate the influence of stirring speed on stir casting synthesis of 15 wt% silicon carbide particle reinforced aluminium alloy (SiCp-6061 Al) composite. The composite samples were produced at different stirring speed of 300, 500 and 700 rpm. However, the processing temperature and time are maintained at 800 °C and 180 secs processing condition. Dry reciprocating wear test is conducted using a ball on disc wear tester at a constant operating condition of 50N load, 10Hz frequency for 30 mins on the samples. The influence of stirring speed on the microstructure and wear morphology is examined using scanning electron microscope (SEM). The result reveals that the stirring speed influenced the processing condition including the microstructure and wear topography. Composite processed at 500 rpm attained homogeneity of the SiCp phase as observed from the microstructure. The worn surface experiences a relatively smooth mild wear without formation of cracks, porosity and craters. However, at 300 rpm the composite experiences micro cracks with formation of abrasive grooves due to insufficient distribution of the SiCp phase. Moreover, at 700 rpm high speed vortex formation is observed due to vigorous stirring which entraps gases and develops into large porosity, cracks and deep craters. This study establishes that stirring speed has a significant effect on the processing condition as well as the wear morphology of SiCp-Al6061 composite developed using stir casting technique.Keywords: Stir casting, Stirring speed, Wear morphology, SiCp-6061Al composite, Microstructure 1 INTRODUCTION Silicon carbide particles reinforced aluminium alloy (SiCp-6061Al) composite is the most commonly used metal matrix composite due to its strength and stiffness, improved wear resistance and cost effective process technique [1]. These features makes them to emerge as an important category of materials that have potentials for structural applications in the automotive and aerospace industry. The processing of this attractive material plays a major role in determining the performance properties under operational condition [2,3]. Among the variety of processing technique, the stir casting is generally accepted and commercially viable in developing the aluminium silicon carbide composite [4]. Moreover, the properties of SiCp-6061Al composites produced by stir casting depend on process parameters such as stirring speed. For instance, the homogenous distribution of reinforcement particulate is mostly dependent on the stirring speed of the composite melt. Uniform distribution is desired in order to maximize the composite properties. In achieving these properties, the stirring speed is of utmost concern.Several casting defects are obviously related to the extent and method in which the stirring occurred. Studies [2,4] have shown that porosity formation is attributed to gas entrapment during vigorous stirring leading to air bubbles in the slurry either independently or as air envelopes the reinforced particles.

“…This degrades the aggregate properties leading to brittleness, poor machinability, and reduced fracture toughness of the AMC's [25,26]. In addition to this, ceramic reinforcements in Al composites reduce the impact strength of the composites by reducing strain energy and forms regions of stress concentration [27]. Under these conditions, the development of agrowaste AMC's is quite beneficial.…”

Aluminum matrix composites (AMCs) have been extensively studied primarily due to higher strength-to-weight ratio, lower cost, and higher wear resistance properties. However, increasing demand for economical and energy-efficient materials in the automotive, aerospace and other applications is tailoring research area in the agro-based composite materials. Therefore, the aim of this systematic review work is to study the influence of agro-based reinforcements on the tribological and mechanical properties of AMC's processed by various techniques. It was observed that the processing conditions can be designed to obtain uniform structures and better properties AMCs. The agro-waste reinforcement materials, such as rice husk ash, bamboo stem ash, coconut and shell ash can result in a reduction in the density of AMC's without compromising mechanical properties. Moreover, the efficient utilization of the agro-waste leads to a decrease in manufacturing cost and prevents environmental pollution, hence, can be considered as a sustainable material. The state-of-the-art revealed that the agro-based reinforcements do not form brittle composites, as in the case of ceramic reinforced composites. Hence, the study concludes that the agrobased AMCs have great potential to act as a replacement for costly and environmentally hazardous ceramic reinforced-AMCs which can especially be used in various automotive applications that demand higher strength-to-weight ratio, lower cost, and higher wear resistance.
