Study of the substructure of the tungsten carbide powder during milling by radiography methods

Abstract

Methods of X-ray diffraction study on the defect structure of tungsten carbide powder during long-term (72 hours) grinding the batch of alloy WK8 in a ball mill in the environment of acetone. Investigated the physical profiles of the diffraction peaks, calculated by direct solution of the convolution equation with the sustainable use of Tikhonov's regularization method. The results of the analysis of shapes and widths of X-ray diffraction lines are compatible with the idea of the formation during milling of heterogeneous defective state of the powders of tungsten carbide and a bidispersity their coherent scattering regions, with nanosized component.
