Abstract

A dependence is given for porosity of iron powder and iron-graphite composite based on atomized and reduced powders on different electric-contact compaction regimes. A dependence is determined for the amount of bonded carbon on process regime. Limiting processes are established during formation of powder steel by electric-contact compaction.
