Abstract
The microstructural changes were investigated in an Al-Cu-Mn alloy reinforced with SiC particles after being kept in the liquid or semi-solid state. The microstructural and compositional changes were characterized by differential thermal analysis (DTA), X-ray diffraction, and scanning electron microscopy (SEM) equipped with an energy dispersive X-ray analysis (EDXA) system. The solidification behavior of the monolithic alloy is followed by the Al-Cu-Mn ternary system while its composites showed the Al-Cu-Mn-Si quaternary system due to the rejection of Si from SiC particles after being kept in the liquid or semi-solid state. SiC particles were attacked heavily and a large amount of reaction product, Al 4 C 3 was formed. The extent of reaction was calculated from the contents of Si in matrix by the DTA method for determining the liquidus. The result was compared with the quantitative metallography.
