Remarkable promotion of mechanical tensile strength of Mg1-xAxB2 superconductor via additions of ultra-high - ductile AZ61-alloy

Extruded Mg-(6%Al)-(1%Zn) ∼ (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, x = 0.0,0.025,0.050,0.075 and 0.1 mol and A = 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 760 °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 52.3 MPa is for sample with x = 0.075 mol which is better than pure MgB2 (33.8 MPa.) by promotion ratio∼ 54.73%.
