“…Furthermore, the nearly low-turbulent inflow resulted in wetting of the CFFs with an approximately constant flow length and temperature (C722 °C, see Figure 2c). The castings behind the filter chamber also showed an approaching consistent temperature field (between 626 and 713 °C), indicating a temperature close to the liquidus temperature (626.33 °C) of this alloy system according to Luo et al 40 The uniform mold filling conditions behind the filter are emphasized by the absolute velocity at pouring time of 3.604 s (Figure 2d), as the CFF further act as velocity or flow modifier, resulting in a continuous velocity of below 0.5 m/s.…”

In this study, filtration of aluminum alloy (Al) with different weight fractions of SiC particles (SiCp) was investigated. Therefore, three different filter materials of 20 pores per inch (ppi) ceramic foam filters (CFF) were tested. A special three-chamber furan mold was used for the casting trials to provide uniform filling and flow conditions for the filtration process. Samples from sections of the gating system, as well as from the filter, were analyzed by optical light microscopy to determine the amount, size, and distribution of SiCp. A scanning electron microscope (SEM) with energy-dispersive X-ray spectroscopy (EDS) was used for obtaining the element distribution in the composite. The filtration efficiency increased by decreasing the weight fraction from 20 to 5% of SiCp and reached a significant particle reduction of over 90%. Investigations of CFFs with a weight fraction of 10% have shown a clogging effect and metal flow interruption through the 20 ppi filter. An oxide layer was detected around the respective SiCp in the EDS. Moreover, a strong accumulation effect was observed, indicated by a steadily flattening curve of the density functions after each additional remelting cycle of the same composite material.

“…MMCs show better mechanical and thermal properties like high strength, high-temperature resistance, and ductility on the other hand they depict low stiffness because of the strong but brittle properties of ceramic reinforcement particles [33][34][35][36][37][38][39][40][41]. For example, Al (Metal Matrix) -SiC (refractory ceramic reinforcement in particle form) composite shows in-between mechanical and thermal properties as strength, wear resistance, electrical and thermal conductivity, coefficient of thermal expansion and stiffness, etc.…”

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.
