Abstract

Quantitative fractal analysis of the microstructures of in situ Al–15%Mg2Si composite with and without Bismuth (Bi) has been performed. Fractal dimension of primary Mg2Si particles and eutectic Mg2Si network were calculated by box counting method. In this study, we attempt to show the modification effect of Bi addition (0–0.3%wt.) on fractal dimension of Al–15%Mg2Si microstructure. Also, efforts were made to establish a correlation between the fractal dimensions of Mg2Si (primary and eutectic) and ultimate tensile strength (UTS) and elongation (El.%) values. The results show that by addition of Bi, there is a linear correlation between UTS and the fractal dimensions of primary Mg2Si particles; however, no connection between fractal dimension of eutectic Mg2Si and UTS and El.% could be detected.
