Abstract
The microstructure of the interface of the explosively welded tantalum-steel composite which had been subjected to heat treatment at 1053 K was investigated by using optical microscopy and electron probe micro-analysis. It was confirmed that a Ta2C layer grew along the tantalum-steel interface. The carbon diffusion path at 1053 K, going through the γ-Fe, α-Fe, Ta2C and α-Ta phase regions was identified and interpreted by means of the Fe-Ta-C equilibrium phase diagram assuming that local equilibrium is established at all the phase boundaries.
