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.

Highlights

IntroductionF. The combination of properties (such as high modulus and strength, high abrasive wear resistance, high toughness, and low deformation) are highly desirable in the areas of aviation, electronic devices, automobiles, space shuttles, and marine industries [1,2]
The results showed that quasi-isostatic forging (QIF) plates have higher ductility but a lower strength compared to hot isostatic pressing (HIP)/high-strain-rate forging (HSRF) plates
This study provides the following conclusions: (a) the wear rate increases, as the grinding speed increases; (b) aluminium metal matrix composites (AMMCs) with silicon carbide (SiC) as reinforcement particles have lower wear rates than AMMCs with Al2 O3 reinforcement particles; and (c) the wear rates for both types of composite materials decrease significantly, as the particle reinforcements increase

Summary

Introduction

F. The combination of properties (such as high modulus and strength, high abrasive wear resistance, high toughness, and low deformation) are highly desirable in the areas of aviation, electronic devices, automobiles, space shuttles, and marine industries [1,2]. Monolithic material’s inability to have this attractive properties combination make metal matrix composites (MMCs) as a suitable successor for monolithic materials, as these desired properties combination can be induced in MMCs [1,3]. Extensive studies carried out in MMC areas reveal that either MMCs are in their developmental stage or their manufacturing processes are still not well-established. The high fabrication cost of MMCs is the biggest hurdle in their applications [4,5]. The fabrication of MMCs demands lower-weight and -density components. Popular matrix materials are aluminium, magnesium, and titanium
