Mechanical Properties of MgB2 Bulk Fabricated by Spark Plasma Sintering

A clear understanding of mechanical properties of superconducting bulk materials is required for their reliable integration together with other materials constituting the superconducting devices. In this study, evaluations of mechanical properties of a high packing ratio MgB2 bulk processed by Spark Plasma Sintering-SPS were carried out. Mechanical properties of the high packing ratio MgB2 bulk processed by SPS were improved than those of MgB2 bulks processed by conventional route. The improvement of the mechanical properties with increasing the packing ratio could be approximated by using exponential equations.
