摘要: Abstract Near dense Mg 0.5 wt.% Zr (0, 1, 2.5 and 4) La alloys were successfully synthesized by disintegrated melt deposition technique followed hot extrusion characterized for their microstructural, ignition, hardness, tensile compression properties. Combined effects of assisted in significant grain refinement 4 exhibited an average size as low ∼2.75 µm. High ignition temperature ∼645 °C was realized with (1, alloys. Microhardness value high ∼103 Hv observed alloy. Under room loading, improvements the strength properties pure addition observed. maximum 0.2% yield strengths ∼283 MPa ∼264 MPa, respectively. The fracture strain values found to be unaffected Zr. But reduced while compressive unaffected. Minimal tensile-compression asymmetry (∼1) (1 2.5)
