Hydrogen Effects in Refractory Metals,rittlement of columbium and tantalum by hydrogen at room temperature and below is usually associated with hydride formation. No investigations have been made of the mechanism of embrittlement by hydrogen at higher temperatures. Columbium and tantalum specimens will fragment when cooled from elevated
