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). Duration of project: 3 years Total amount of funding received (in ECU): 147.500.- Total manpower involved (in man years) 3.5 Number of publications from COST 507-11: 27 (a) number of contributions to scientific journals: 7 (b) number of contriubutions to conferences: 9 (c) other: 11 Publications (Manuscripts or copies of References Nr. 1-6, 13,16,17,19 and 20 have already been submitted as part of the annual reports 1994 and 1995.
