Title: Ordering in niobium monocarbide

Abstract

An attempt is made, on the basis of information obtained in the course of an x-ray diffraction investigation of crystallites separated out of ingots, to summarize data relating to ordering in niobium monocarbide. The x-ray photographs of crystalline niobium monocarbide fragments separated out of annealed alloys with 45% C are shown. It follows from the data that the delta'modification of NbCx is the only ordered phase existing in the homogeneity range of niobium monocarbide. Its diffraction characteristics match fully those found in an investigation of NbCx single crystal with a trigonal elementary cell.
