Conclusions

  1. 1.

    In finding the weakest section in the structure of heterophase brittle materials, if is essential to carry out tests to destruction under controlled conditions, i.e. with slow crack propagation.

  2. 2.

    Data have been obtained for the gradation of weak sections in the structure of a WC-20% Co alloy. It is shown to be possible to establish a correlation between the characteristics of the resistance to failure and a complex of stereological parameters of the structure.

  3. 3.

    Raid deformation may occur during crack propagation in a heterophase brittle material, and in consequence it is difficult to determine the failure mechanism from the form of the fracture.
