“…[29][30][31] On the other hand, the Al-SiC interfaces in the DRA composites act as effective sinks for vacancies and disallow their coalescence. In some of the previous studies [32][33][34][35][36] related to the quenching of DRA composites with age-hardenable alloy matrices, the density of Guinier-Preston (GP) zones was found to be significantly reduced, primarily because of the much lower concentration of quenched-in vacancies in the matrix than that usually found in the unreinforced alloy being subjected to similar heat treatment.…”

“…Apart from time and temperature of ageing critical influence, on the mechanical properties has solution heat treatment temperature. According to Al-Mg-Si phase diagram and literature reports, solution treatment at 558 o C exhibit better strength properties compared to composites treated at 530 o C [11,14]. This is caused by the fact that the melting of ternary eutectic Mg 2 Si-Al-Mg phase takes place at 558 o C and the concentration of alloying elements in the supersaturated solid solution is higher.…”

“…Another reason for slower aging kinetics of composites is presence of voids on matrixreinforcement interface. Coming back to aging kinetics, in other studies, different conclusions were reached [13][14][15][16][17][18]. The authors observed acceleration of aging kinetics with an increase of reinforcement volume fraction.…”

“…The number of elements of the solid solution in the matrix, which can form GP zones, is constant, and it will inevitably cause a decrease in GP zone density. [12][13][14] When the temperature reaches 160 °C, the peak of the composite material is the highest, but the ageing time is too long (it needs 15 h). Therefore, the ideal application is ageing treatment of the composite materials at 180 °C for 6 h, which is based on the best solid solution treatment.…”
