    摘要: A capacitor-grade wire made from powder metallurgy containing at least niobium and silicon, wherein the niobium is the highest weight percent metal present in the niobium wire. The wire having a controlled tensile strength at finish diameter exceeds the strength of capacitor-grade wire formed by ingot metallurgy. Also, the powder metallurgy wire hardness exceeds capacitor-grade wire formed from ingot metallurgy with electrical leakage meeting the specifications normally applied to capacitor grade tantalum, niobium or niobium-zirconium lead wire at sinter temperatures of about 1150° C. and above.

    摘要: A process for producing a wrought product of improved ductility from substantially noncompactible prealloyed metal powder. The process comprises the steps of: comminuting substantially noncompactible prealloyed metal powder so as to flatten the particles thereof; heating the comminuted particles of metal powder at an elevated temperature, the particles adhering and forming a mass during heating; crushing the mass of metal powder; compacting the crushed mass of metal powder; sintering the metal powder; and hot working the metal powder into a wrought product. The wrought product has a chemistry which is substantially the same, with the exception of carbon and certain residuals, as the chemistry of the prealloyed powder.
