| Abstract Scope |
One of the main challenges in the in-situ manufacturing of lightweight Al-base Metal Matrix Composites (AMMCs) is the pushing-engulfment phenomenon, particle interaction, and particle-matrix reactivity. This study aimed to determine the influence of the chemical composition of the Al-base matrix on these phenomena. Additionally, the effect of TiC particle distribution on mechanical properties was analyzed. The research focused on three types of AMMC matrices: Al 1000, Al-7%Si, and A356, each reinforced with 10 wt% TiC reactants. The results indicated an increase in TiC particle size for Al-7Si and A356 compared to the Al 1000 alloy. An inter-dendritic distribution of TiC particles was observed in the Al 1000 matrix, whereas an inter-eutectic distribution was noted in the Al-7Si and A356 matrices. The greatest increase in tensile strength was observed in the Al 1000 matrix, followed by the Al-7Si alloy. Controversy, the A356 alloy exhibited the least relative increase in tensile strength. |
