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.

“…In recent years, nano-sized ceramic particles such as SiC and Al 2 O 3 have been used to reinforce a metal matrix, so-called nano-sized ceramic particle reinforced aluminum matrix composites (NCPRAMCs) [32][33][34]. An electromagnetic stirring method was employed to fabricate NCPRAMCs reinforced with a variety of nano-sized ceramic particles such as TiC, Al 2 O 3, and B 4 C [35][36][37][38][39][40]. In addition, adaptive-network-based fuzzy inference system (ANFIS) and particle swarm optimization (PSO) were used to optimize the process parameters such as mold temperature, mix time, size of reinforcement, and volume fraction of reinforcement [35][36][37][38][39][40].…”

Semisolid billet of the 7075 aluminum matrix composite reinforced with nano-sized SiC particles was first fabricated by an ultrasonic-assisted semisolid stirring method and rheoforming technology. Then it was thixoformed into a cylinder part under different remelting temperatures and soak times. The effects of the remelting temperature and soaking time on the mechanical properties and microstructure of the thixoformed composite part were investigated. The results show that parts of good quality were thixoformed successfully. The microstructure of the top side wall of the thixoformed part consisted of near spheroidal grains. A large quantity of elongated grains occurred in the medium and bottom side walls and the bottom itself. With increasing remelting temperatures, the size of the solid grains of the thixoformed parts showed a trend of first to increase and afterwards to decrease. High density dislocations were found in the microstructure when the remelting temperatures were 590 °C and 600 °C. When the soaking time was 15 min, the severest deformation occurred in the thixoformed part. High mechanical properties of the thixoformed parts were achieved under conditions such as a remelting temperature between 590 °C and 600 °C and a soaking time between 10 min and 15 min. The fracture mode of the thixoformed part changed from transgranular fracture to intergranular fracture when the remelting temperature was elevated from 580 °C to 610 °C. After the thixoformed parts were treated by T6, the ultimate tensile strength (UTS) and elongation of the side wall were improved to 552 MPa and 7.9%, respectively. Dispersed MgZn2 precipitates created by T6 heat treatment led to an improvement of the mechanical properties.
