Microstructure and hydrogen permeation of Nb 56x W x Ti 23 Co 21 (x = 0, 5, 10) alloys have been investigated. The alloying effect of W on the hydrogen diffusivity of Nb 56x W x Ti 23 Co 21 alloys was discussed from a perspective of the chemical potential of hydrogen under nondilute condition. All ascast ingots were consisted of primary bcc(Nb) and eutectic (bcc(Nb)+B2TiCo) structure.
