Abstract
Abstract
The localization of impurity phases in ceramics created by direct nitridation of zirconium rolled metal was established. For ceramics synthesized at temperatures above the melting point of the metal, the impurity phases are localized along grain boundaries and at macrodefects. In a composite heterostructure of the composition ZrN –(ZrN
x/α
--solid solution of nitrogen in metal/ZrN
x
) – ZrN, impurity phases are predominantly localized in an α-solid solution of nitrogen with their subsequent displacement to grain boundaries and macrodefects at the end of the nitridization process.
