Abstract: The Ta2C layer formed in the bonding interface of a tantalum clad steel composite with an intermediate layer of pure iron at 1 053 K for different times was examined metallographically and analyzed using the electron microprobe technique. The mechanism of Ta 2C phase diffusion layer formation was discussed using Fick's law assuming that stationary diffusion of carbon was established in tantalum/steel diffusion couples.
