- Title
Surface Carbides in the Sequence of Phase Equilibria in a Binary (Tungsten–Carbon) System.

- Abstract
The place of surface carbides in the sequence of phase equilibria is considered as reflected by the tungsten-carbon equilibrium phase diagram. It is shown that the temperature dependence of the critical concentration of dissolved carbon, at which the surface carbide formation on the (100)W single crystal face is completed, is described by a curve lying in the bulk-single-phase region of the W-C solid solutions and dividing this region into two parts (α phase vs. α + surface carbide). An approximated formula is suggested that describes the critical concentration-temperature relationship.
