ABSTRACT

This chapter highlights the important parameters that affect the performance of stir casting performance and recent advancements in the class of hybrid composites. Giving a brief introduction to alloy, composite elements, and recent trends in advanced hybrid metal matric composites (AMMCs) has been discussed in good detail. Then, the introductory part merges to property benefits of composites over alloys.

In the next section, various production methods of metal matric composites (MMCs) are discussed in detail. The merits and demerits of each production process with a targeted application are explained. After that, the section merges with stir casting types and influences of various parameters/attributes such as stirring speed, stirring time, blade angle, stirrer size, the position of the stirrer, and feed rate of reinforcements, etc.

In the following sections, the authors have discussed the parameters affecting MMCs and reinforced material properties of the MMCs. Hybrid composites (h-AMMCs) are explained in great detail. This section comprises an introduction to hybrid MMCs, application of AMMCs, recent studies related to microstructure, physical, mechanical, tribological, and corrosion resistance of h-AMMCs.

In the last section, the wet tribology of hybrid composites is discussed. Mechanistic studies related to dominating wear mechanisms, tribolayer effect, and friction/lubrication principle are discussed with suitable illustrations. An important study associated with improved thermophysical properties is also discussed, which enhances the reader’s viewpoint regarding surfactant-assisted oil dispersions. Then the chapter closes with significant knowledge about the major challenges and conclusions of production and wet tribology of MMCs.
