thermodynamic optimization. A full set of thermodynamic data has been published for
W-B (Ref. 19) and is provided for W-B-C (Ref. 20).
Hf-C, Zr(Hf)-B-C with group UK1 (NPL-London): The subsystems Hf-C Ti-Zr-B,
Ti-Hf-B, Zr-B-C, and Hf-B-C have been assessed and calculated by thermodynamic
optimization (Ref.21 to 25). A full set of thermodynamic data has been provided.
Difficulties in the binary boride evaluation have forced a calculation and optimization
of the data sets on the basis of ternary boride systems (26, 27).
