Dependence of the Strength of Powder Steel Formed by Electro-Contact Compaction on Iron Powder Preparation Method

  • Published:
Metallurgist Aims and scope

Results are presented for the dependence of ultimate strength on electro-contact compaction parameters for an iron-graphite composite based on sprayed and reduced powders. A production regime is determined for electro-contact compaction providing the formation of powder steel with maximum ultimate strength. The dependence of ultimate strength on residual porosity is considered.
