Abstract:

Precursor materials for superconductors such as Nb3Sn and Nb3Al include low melting point components. Therefore, conventional extrusion processes with large area reductions are not possible because adiabatic heating raises the temperature above the melting point. In certain circumstances, hydrostatic extrusion could be used, as it can be operated at low enough speeds to allow the deformation heat to dissipate without raising the temperature excessively. However, existing hydrostatic extrusion presses do not have sufficient extrusion volumes to process the large billets required for future magnet applications. This project will combine hydrostatic extrusion and cold drawing to produce relatively large area reductions (~ 4:1) with acceptable adiabatic heating levels. The process can be scaled up to handle billets that can produce single pieces with lengths of 10,000 meters of 1.0 mm diameter wire. In Phase I the process will be simulated with an existing small hydrostatic extrusion press that will be fitted with a draw bench. This will allow the process variables to be measured and the necessary control system to be demonstrated. A preliminary design of a pre-production scale facility will also be completed.
