Commercialization of the developed technology is a prime factor for any nation and sector to retain its existence in this global economy. Day by day the technological advancement touching new high in various sectors like the automobile and aircraft industries but high design efficiency is achieved only when it is complemented by appropriate material. In the list newer addition is MMCs (Metal Matrix Composites) which are favorable because of their lower cost achieved by cheaper reinforcement, easy processing, and capabilities of mass production. In recent days, the importance of semi-solid casting has been well accepted among various processing routes for aluminum alloys despite many challenges in terms of process parameters like porosity, agglomeration, non-uniform reinforcement particle distribution, low wettability, and engulfment, and this is a main consideration for the present work. Semi-solid casting is considered to be one of the most important and effective manufacturing processes of aluminum alloy for viable mechanical and metallurgical properties in the current perspective of product requirement and competitiveness. A glimpse of the current status is presented, which shows the potential of the process which can be utilized by the industries for several benefits. In a nutshell, it can be found that process has the capability of alteration by the use of different scraps and also have flexibility according to the processing parameters like stirring, pouring temperature, type of reinforcements, etc.

The growth of the industrial sector has resulted in a higher use of Aluminium Metal Matrix Composites (AMMCs). These composites are well-known for their exceptional mechanical and tribological qualities, attracting worldwide attention, especially in the automotive, architectural, and aerospace industries. Advanced Metal Matrix Composites (AMMCs) exhibit increased specific strength, improved strength-to-weight ratio at increasing temperatures, and better wear resistance when compared to the basic matrix without any additional components. SiC and B4C particle reinforcements are used to enhance the metallurgical and mechanical characteristics of the base matrix. Authors have used several production methods such as Powder Metallurgy for solid-state procedures and Stir Casting, Compo-casting, Squeeze Casting, and in-situ casting for liquid-state processes to create AMMCs. Stir casting is the most cost-effective and easy process for producing AMMC. This article provides an in-depth explanation of the procedure for producing Aluminium Matrix Metal Composites (AMMCs) utilising AL-7175 as the matrix material, together with B4C and SiC as reinforcements, with the stir casting technique.

“…It also has high fracture toughness, corrosion resistance, and excellent moulding performance. Designated as a super-high-strength deformation aluminium alloy, this material has strong mechanical qualities and resistance to corrosion, rendering it highly adaptable for a wide range of applications [1][2][3][4]. Its qualities are governed by aluminium compound particulates, liquid solution particulates, granular construction, as well as dislocations, and it is an essential component of construction in the aeronautical as well as automobile sectors [5][6].…”

This research primarily focuses on Aluminum hybrid compounds that have extensive applications throughout every realm of manufacturing. Hybrid metal Matrix Composites possess greatly improved physical properties and find extensive utilization across several sectors, including vehicle components and even aviation. The investigation entails using aluminum (Al-7075) as the foundational component and then incorporating iron oxide and PKSA in weight ratios of 3%, 6%, and 9% to fabricate a strengthened Hybrid Metal Matrix Composite. A manufacturing stir-casting technique is being utilized for the fabrication of such compounds. Stirred molding technology is selected because of its advantages, including a very straightforward manufacturing process, cost efficiency, and reliable distribution of reinforcement particles. The inclusion of overall reinforcement grain Fe3O4/PKSA is essential to defining technical composite qualities. The current examination indicated enhancements in physical properties, including elasticity, compression, as well as toughness strength. A longitudinal value at a 9% wt. strengthened Fe3O4/PKSA is found to be the highest at 342 MPa, while the yield strength is measured at 248 MPa, as equated to a standard Al-7075 alloy. Furthermore, the recently manufactured Al-7075/ Fe3O4/PKSA HMMC were subjected to microstructural examinations using SEM and EDS methodologies. The investigations demonstrated a uniform and homogeneous dispersion of Fe3O4/PKSA reinforcement particulates inside the mixture matrix.
