Features of Powder Steel Formation with Electric-Contact Compaction

  • T. A. Litvinova
  • S. N. Egorov

Conditions are analyzed for powder steel formation with electric-contact compaction (ECC). Areas of production regimes with different ratios of moving and retarding surface consolidation between interparticle surface growth (IPSG) migration forces and areas of ECC production regimes, providing homogenization of an iron-graphite charge and high quality consolidation between particles, are indicated. The dependence of steel true ultimate strength on electric-contact compaction regime is considered.
