“…Nampoothiri et al (2018) produced AA356/Sr through stir casting and reported increased porosity and eutectic Si decreased length. Murthy et al (2017) through ultrasonic assisted stir casting produced AA2219/Al 2 O 3 composite. They found that tensile strength of the composite was better than that of the base; this increment was because of grain refinement and degasification.…”

Purpose This study aims to analyse the changes in mechanical and wear performance of aluminium alloy when yttrium oxide particles are incorporated. The microstructures are studied to analyse the change in the grain structures. Worn surfaces are observed via scanning electron microscope to study the wear mechanism in detail. Design/methodology/approach Stir casting is used to incorporate varying composition of yttrium particles, having an average particle size of 25 micrometer, in aluminium alloy 6063 matrix. Wear testing is carried out by DUCOM manufactured high temperature rotatory tribometer, and an indentation test is used for analysing the microhardness of the fabricated samples. Findings Microhardness of the material is increased with the increasing content of particulate addition. With the increasing content of reinforcement, more refined grains are produced. The load is transferred from the matrix to more rigid yttrium oxide particles. These factors contributed to escalated microhardness of the reinforced samples. Particulate addition enhanced the wear performance of the material; this might be attributed to increased microhardness and formation of an oxide layer. Originality/value Aluminium composites are finding wide applications in various industries, and there is always a requirement of material with enhanced tribological properties. Yttrium oxide particles exhibit improved mechanical properties, and their interaction with the aluminium matrix has not been studied much in the past. So, in this work, yttrium oxide incorporated aluminium matrix is studied.

Electromagnetic continuous casting technology serves as a significant means for enhancing the casting performance of 2219 aluminum alloy. Investigating the influence of electromagnetic field variations on the solidification process is crucial for studying the microstructure and mechanical properties of electromagnetic cast billets. Through experimental research, variations in the microstructure and mechanical properties were examined for ordinary direct chill casting, as well as three different electromagnetic power casting ingots. The COMSOL software (COMSOL Multiphysics 6.0) was utilized to simulate the temperature and flow field, enabling an explanation of the resulting performance changes. The results showed the effect on electromagnetic continuous casting technology by the electromagnetic field generated by the Lorentz force and melt stirring, improving the melt flow and temperature distribution so that the melt center and the edge of the melt forcible convection were enhanced, thus realizing the tissue refinement, mechanical properties, and Cu element segregation of the improvement. With an increase in electromagnetic power, the distribution of the temperature field was more homogeneous, the segregation phenomenon was more alleviated, and the improvement in mechanical properties was more significant. The optimal microstructure and mechanical properties were achieved at a power of 20.0 kW, with a 74.7% improvement in grain refinement in the center and a tensile strength increase of 30.8%. Additionally, significant improvements were observed in segregation phenomena.

A fundamental understanding of second‐phase reinforcement addition techniques during ultrasonic casting is necessary for the advancement of metal matrix composite manufacturing technology. This review evaluates the comparative efficacy of various addition techniques for incorporating reinforcements under the framework of ultrasonic processing. The evolution of these techniques over time is deciphered in light of the scientific background behind challenges, principles, and methods. Their role in the improvement of microstructure and properties of the composites, intertwined with ultrasonic treatment, is delineated. Techniques introducing greater kinetic disorder during solidification, such as “Stirring” and “Gas‐Assisted Injection” are found to be superior for reinforcement addition. More significant enhancement of microstructural and mechanical characteristics is also obtained in composites manufactured by the techniques with higher kinetics. This culminates in the identification of the limitations and perspectives on the progress of research in this scope. This analytical review of second‐phase reinforcement addition techniques operates as a tool for researchers to steer the advancement of future procedures and therefore metal matrix composite manufacturing technology.
