Consolidation and mechanical properties of ZrCu39.85Y2.37Al1.8 bulk metallic glass obtained from gas-atomized powders by spark plasma sintering

This manuscript proposes subjecting gas-atomized powders of ZrCu 39.85 Y 2.37 Al 1.8 metallic glass to spark plasma sintering (SPS). bulk (BMG) sinters at a temperature between its crystallization (T x ) and transition g temperatures, found be 457 °C 368 °C, respectively, via Differential Scanning Calorimetry (DSC). Several samples were sintered different temperatures within the mentioned range (380, 390, 400, 415 430 °C). Experimental results confirmed successful BMG by SPS 390 pressure 35 MPa. Fully amorphous compacts with almost 100% relative density this temperature, reaching Young's modulus, Vickers hardness compression strength values 64.7 GPa, 396 HV0.3 1174 MPa, respectively. Sintering higher involved sample. Results suggest that fabricated is promising material for applications in sectors, particularly jewelry, due wear resistance conferred hardness. • obtained starting from gas atomized powders. The obtaining alloy takes only place on narrow temperatures. Bulk discs suitable properties when °C. densification was achieved comparable others Zr–Cu BMGs.
