Abstract
Extruded Mg-(6%Al)-(1%Zn) â¼ (AZ61) alloy powder was applied as softener matter and grains sizes promoter in narrow range to replace on magnesium sites of Mg1-xAxB2 superconductor (where, xâ¯=â¯0.0,0.025,0.050,0.075 and 0.1 mol and Aâ¯=â¯AZ61) alloy) . Samples were synthesized via high temperature solid state reaction technique depending upon diffusion mechanism of Mg -vapor ions through added A-boron-matrix at 760â¯Â°C. Micro-structural features and grains sizes averages were estimated and monitored by both of 3D-AFM and SE-microscopy. Mechanical tensile was recording promising results with maximum tensile value of 52.3â¯MPa is for sample with xâ¯=â¯0.075 mol which is better than pure MgB2 (33.8â¯MPa.) by promotion ratioâ¼ 54.73%.
