Stochastic mechanism of deformation of flowing powders in the incoherent zone during rolling

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    It is demonstrated that the stochastic mechanism of powder deformation in the incoherent zone can be satisfactorily explained in the light of information on the discrete mechanism of motion of flowing powders under the action of gravity.

  2. 2.

    The existence is shown of two kinds of nonuniformity of powder deformation in the incoherent zone, on the submacroscopic and macroscopic levels.

  3. 3.

    Nonuniform deformation of powders in the feed zone is preserved in the rolled strip, and may give rise to a large scatter of its structure-sensitive properties.
