Abstract
High-purity electron-beam-melted columbium was doped up to levels of 15 at.% with nitrogen, hydrogen, or oxygen, the precision lattice spacing measured, and the superconducting transition temperatures determined. The relationship between transition temperature and volume change developed for substitutional alloys is shown to be valid also for interstitial gaseous impurities. Beyond the effect each gas had upon lattice distortion, no critical temperature characteristics were observed which were dependent upon the specific element.Keywords
