Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): РОДИЙ -- РЕНИЙ -- КАРБИДЫ -- МИКРОТВЕРДОСТЬ Аннотация: The products of the thermobaric treatment (P = 1-4 GPa, T = 2000C) of the ultrafine powder Re0.67Rh0.33 (crystallite size 50 Å) were studied. For one of the products, the (Vickers) microhardness is 1200 kg/mm2, which is significantly higher than the literature values for alloys in the Re–Rh system. This effect is attributed to the formation of a binary carbide with an anti-NiAs type of structure Полный текст |
