Abstract
The microstructure of nanocrystalline nonstoichiometric atomic number 41 carbides NbC0.77, NbC0.84, NbC0.96 powders created by high-energy ball edge has been investigated by time-of-flight (TOF) high resolution nucleon optical phenomenon. The optical phenomenon patterns are collected with the high resolution Fourier diffractometer HRFD by exploitation the TOF mode of information acquisition. The nanocrystalline ball-milled powders have a microinhomogeneous structure, within which 2 fractions with totally different particle size and composition may be known. the common sizes of the coherent scattering regions and microstrains in nanocrystallites with allowance for the property of the deformation distortions are calculable. it's shown that TOF nucleon optical phenomenon patterns will offer the terribly correct information for microstructure analysis of nanocrystalline powders.
Keywords:
Time-of-flight nucleon optical phenomenon, high-energy ball edge, atomic number 41 inorganic compound, nanocrystalline materials, microstructure.
