In the present work, an attempt has been made to study the microstructural and mechanical behaviour of Mg-alloy prepared by powder metallurgy process. Highly pure Mg powder is used for the fabrication of Mg-alloy at different additive percentages. The investigation of constituent phases was successfully completed for the Mg-alloy using standard X-ray diffractometers. Scanning electron microscopy was used for the morphological studies. Tensile strength and percentage elongation of Mg-alloys were also evaluated at room temperature. The minimum and maximum ultimate stress varies from 67 to 108MPa. The percentage elongation also increased 1.03 to 1.57%.
