External friction in the process of SHS-compaction
Keyword(s):
On the basis of previously developed rheodynamic models of high-temperature SHS‑compaction, a theoretical analysis of the process of backward pressing with the active action of external friction force was carried out. It is shown that in this version of extrusion external friction is a useful technological effect, which allows to obtain a uniform distribution of density over the volume of the pressing material. Analytical relationships have been obtained for calculating the characteristic pressing time and stress distribution.
