Conclusions

  1. 1.

    The nonuniformity of deformation in the lower part of the feed region exhibited by metal powders being rolled is due to the action of tensile stresses.

  2. 2.

    A diagram has been constructed (Fig. 2) with the aid of which it is possible to determine conditions under which no disturbances arise during the rolling of metal powders.

  3. 3.

    During the rolling of metal powders, their deformation in the lower part of the feed region is characterized by a volume scheme of principal strains, Dv = (−+ +).
