Abstract:
1. A process for making a silicone-doped niobium lead wire comprising: (a) forming a low oxygen niobium powder by hydriding a niobium ingot or a niobium bar and grinding or milling the ingot or the bar, and thereby making a powder having a Fisher Average Particle Diameter particle size range of less than 150 microns; (b) (i) dehydriding the niobium powder, and (c) blending the low oxygen niobium powder with a silicon additive powder, and compacting the powder blend of low oxygen niobium powder and silicon additive powder by cold isotactic pressing to form a bar; (d) thermomechanically processing the bar into a rod; and (e) subjecting the rod to the following sequential steps,
