中文摘要	(w0.5al0.5)c-0.5 substoichiometric compound is synthesized by a combination of mechanical milling and high-pressure reactive sintering. x-ray diffraction is used to monitor the phase changes and crystallization of (w0.5al0.5) c-0.5 during the whole reaction process. as a result, (w0.5al0.5) c-0.5 is identified as the hexagonal wc-type belonging to the p-6m2 space group (no. 187), and the lattice parameters of (w0.5al0.5)c-0.5 are calculated to be a = 2.907 (1) angstrom, c = 2.838 (1) angstrom, which are very similar to those of wc even if there are approximately 50 pct carbon vacancies in the cell of (w0.5al0.5)c-0.5 as compared with wc. the substoichiometric (w0.5al0.5)c-0.5 compound has a vickers microhardness of 2385 +/- 70 kg mm(-2), which is as high as that of wc, while its density is far lower than that of wc.
