This paper presents the results of an automatic analysis of the structure of tungsten-cobalt sintered carbides with 6-25% weight of the binder phase and shows the possibility of their practical use for improvement of the mechanical properties of the materials. The authors conclude that accurate determination of the structural parameters of sintered carbides has made it possible to establish the yield strengths of the matrix material of different types of tungsten-cobalt sintered carbides and to determine those for which an increase in crack resistance is possible. The effect of the increase in fracture toughness of sintered carbides with an increase in loading rate is also explained.
