“…With a rise in RM, the hardness property of the composite raised up to 45% for both the alloys, before and after ECAP and the obtained results are consistent with G. et al [3]. The enhancement property is probably due to the RM particles, which fill up the voids and harden and refine the grains during the ECAP process and the formation of UFG in the reinforced material 19) .

We reinforced aluminium matrix composites with three different amounts of red mud. These red mud reinforcements were manufactured using stir casting and then subjected to ECAP for evaluating the structural and wear behaviour. The formation of submicron size grains significantly enhanced the hardness, which in turn significantly lowered the loss of wear for ECAPed composites. A reduction in the wear rate was noticed with the rise in the percentage of RM reinforcement. Before ECAP, the least wear impact noted was in the composite that had 10 weight percent reinforcement. After ECAP, the least wear rate was found in the composite that had 15 weight percent reinforcement. The wear rate might have been minimized because of the elimination of the oxide layers after ECAP. At higher loads, the frictional thrust increases, consequently increasing the de-bonding and detaching of the material. Therefore, a rise in normal load raised the wear rate.

“…Reducing mixture viscosity and consequently increasing the mixture fluidity is one of the most significant advantages of the compo casting process [50][51][52][53][54][55]. It has been proven that the injection of the second phase into the semi-solid mixture entraps reinforcing materials in the solidifying metal matrix and prevents algorithmization and settlement [56][57][58]. In this research, the effect of the casting method on the mechanical properties of A356-Al 2 O 3 composite with different content of reinforcements is investigated.…”

This study investigates the effect of casting methods, content and size of reinforcing particles and heat treatment on the mechanical properties of A356-Al2O3 composite. First, composite samples were made by three methods: gravity sand casting, squeeze casting, and semi-solid compo casting, and then some of them were subjected to the T6 heat treatment. Test specimens were extracted from the samples, and their tensile and yield strength, elongation, and porosity were measured, analyzed, and compared. In addition, the microstructures of composites made by nano and micro scale reinforcing particles were studied and compared. It was concluded that the superior mechanical properties were obtained in samples made by semi-solid compo casting using nanoscale reinforcing secondary phase and subjected to the T6 heat treatment.
