A Contemporary Review of Aluminium MMC Developed through Stir-Casting Route

Abstract

The growing demand for composite materials with improved properties is attracting a lot of attention from industries such as automotive, aerospace, military, aviation, and other manufacturing. Aluminium metal matrix composites (AMMCs), with various reinforcements such as continuous/discontinuous fibers, whiskers, and particulates, have captured the attention due to their superior tribological, mechanical, and microstructural characteristics as compared to bare Al alloy. AMMCs have undergone extensive research and development with different reinforcements in order to obtain the materials with the desired characteristics. In this paper, we present a review on AMMCs produced through stir casting routes. This review focuses on the following aspects: (i) different reinforcing materials in AMMCs; (ii) microstructural study of reinforced metal matrix composites (MMCs) through stir casting. Both reinforcing micro- and nanoparticles are focused. Micro- and nanoreinforced AMMCs have the attractive properties of combination such asthe low-weight-to-high-strength rati and, low density; (iii) various tribological and mechanical properties with the consideration of different input parameters; (iv) outlook and perspective.

Insitu synthesis of Al– MgAl2O4 composites and parametric optimization of tribological characteristics

“…Fabrication of aluminum metal matrix composites are mainly carried out through stir casting, squeeze casting, powder metallurgy, centrifugal casting, ultrasonic assisted casting etc. in which stir casting technique is the most economical technique which has gained interest with the researchers [ 13 , 14 ]. However when it comes to the fabrication of aluminum composites with minimal particle size, formation of reinforcement clusters happens with nominal wettability thereby reducing the quality and properties of developed composites.…”

“…The microstructure analysis also showed uniform distribution of aluminium oxide particles. The researchers used a variety of reinforcing materials, such as Al-based MMCs with superior mechanical properties in their study by Yadav et al (2021). By using powder metallurgy, they studied the effects of adding SiC/CNT in combination as reinforcements.…”

“…Microstructure analysis conveyed that reinforcement particles were distributed uniformly since stir casting was chosen as the method of fabrication. Yadav et al [5] reviewed the works on stir-casted aluminium metal matrix composites. Apparently, the inclusion of SiC as the reinforcement material resulted in improved mechanical properties.…”
