Abstract : The structural diagram of the UC-W system was constructed. This diagram is of the eutectic type with a limited solubility in the solid state. The melting temperature of the eutectic is 2180 plus or minus 20C. The eutectic point corresponds to 10 wt. % W. The solubility of W at the eutectic melting point is about 8 wt. %. The solubility of W at 2000C is about 4 wt. %. The solubility of UC in W was not observed. The diffusion of U from UC into W was studied in the temperature interval of 1500-2100C. In the investigated temperature interval there is no reaction between UC and W. (Author)
