摘要： A process for the manufacturing of 100% dense TMC bulk material by hot isostatic pressing (HIP) for manufacturing of ternary molybdenum chalcogenide (TMC) single or multifilamentary superconducting wires, in particular that of SnMo6S8 (SMS) and PbMo6S8 (PMS). Such wires allows generation of magnetic fields in excess of 24 Tesla, the limit of the presently used Nb3Sn wires. In addition, TMC superconducting wires are complementary to Nb3Sn because they have about four times higher mechanical strength, i.e., yield strength Rp02. The deformation process by hot extrusion and the hot wire drawing allow plastic/superplastic deformation of the TMC superconductor with perfect grain boundaries, increase the critical current density. Further, the use of high purity molybdenum, with a residual resistivity ratio of at least 100, is considered as an additional inventive step because molybdenum serves not only as a diffusion barrier but simultaneously as electrical stabilizer.
