<br/><br/> A series of Aluminum Magnesium alloys with highand lowlevels Magnesium with addition of high and low levels of Zirconium and Samarium was prepared.Thermal analysis was implemented by using thermocouple K-type to investigate the effect of Zr and Sm addition.Microstructure was examined by optical microscopy and scanning electron microscopy. It was found that intermetallic phases are transformed into Chinese script structure when adding Sm for both high and low level of Mg addition in Al-Mg alloys
