The Nb 2C layer formed in the bonding interface of a niobium clad steel composite at 1023 K for 112 h was examined metallographically and analyzed using the electron microprobe technique. The mechanism of Nb 2C phase diffusion layer formation was discussed using Fick′s law assuming that stationary diffusion of carbon was established in niobium/steel diffusion couples.
