The current study investigated the effects of gadolinium (Gd) addition (0, 0.3, 0.5, 1.0, and 2.0 wt%) on microstructural development and solidification characteristics of hypereutectic Al-15%Mg2Si in-situ composite. Microstructural examinations were carried out via optical microscopy (OM), scanning...
