Magnesium-zinc alloys offer promising lightweight properties but are prone to oxidation during high-temperature processing and usage. In this study, the behavior of Mg-Zn alloy was examined according inert gas type flow rate, heating rate amount. Initially, were produced by adding zinc at weight percentages 0.5%, 1.5%, 2% using casting method. The characterized X-ray fluorescence (XRF), Diffraction (XRD), scanning electron microscope (SEM) analyses, revealing formation dendritic intermetallic within alloy. these via differential thermal analysis (DTA) thermogravimetric (TGA), considering factors such as protective atmosphere, amount alloying element. results indicated that onset temperature decreased with increasing rate. effect varied depending on gas. Under a nitrogen conditions 20°C∙min‒1 5 cm3∙min‒1 resulted in least oxidation. an argon found be sufficient prevent However, 1 cm3∙min‒1, more effective preventing element (zinc) likely reduced oxidation, particularly 1.5% addition level, possibly due compounds.
