Conclusions

Some of the key features of experimentally determined overall strain coefficients of metal powders in the relative strip density range investigated are: for the overall height strain coefficient, its comparatively rapid variation; for the overall transverse strain coefficient, its constancy and a high value of strain comparable with that of the transverse strain in the rolling of nonporous solids with a narrow region of deformation; for the overall longitudinal strain coefficient, its growth during the densification of the powder being deformed. The powder densifieation process is less intense in rolling than in pressing according to the D l (−00) scheme.
