Aluminum metal matrix composites (AMMCs) have been identified as one of the promising materials exhibiting excellent structural and functional properties that can be considerably tailored to meet the manufacturing challenges as well as to meet the design standards for many applications such as defense, automobiles, marines, and aerospace. In the existing chapter, an attempt has been made to provide an extensive summary of the various processing techniques for the development of AMMCs, such as powder metallurgy stir casting, ultrasonic probe-based stir casting, friction stir processing, and 3D printing. Powder metallurgy is an alternate way to prepare nanocomposites and composites. Many researchers have attempted to evenly disperse reinforcement particles in the matrix alloy using conventional methods, but they have found them to be ineffective. Among all of the options, they have found that ultrasonic probe-based stir casting is more effective, which has been discussed in detail. In addition, the present chapter also discusses the friction stir processing and 3D printing process. © 2023 Walter de Gruyter GmbH, Berlin/Boston. All rights reserved.
