Manufacturing of β-type NbXTi (X=50 at%)/SWCNTs Matrix Nanocomposites by FAST-SPS: For Metallic Orthopedic Components and Superconductor Magnets in ITER

Abstract

Ti-based alloy, it is desirable to reduce its E to that of healthy bone (4-30 GPa) while maintaining its high strength and good plasticity [1][2][3][4][5][6][7][8]. Two approaches have been taken to achieve this goal. One is the production of metastable β type phase wrought niobium-titanium (Nb-Ti) alloys (for example, Nb50Ti), but the reported minimum value of E (60-62 GPa) is too high [9,10].Alternatively, porous Nb-Ti alloys, having a microstructure similar to that of cancellous bone, have been produced. Nb-Ti Intermetallic compound has been recognized as one of high temperature structural materials due to excellent physical, superconductivity and mechanical
