Effect of reduction temperature on some properties of ultrafine iron powders and hot-forged specimens

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A study was made of the processing properties of a reduced ultrafine electrolytic iron powder. The key parameter determining these properties is powder reduction temperature, which controls also the density of finished parts. An investigation into the process of structure formation during the heating of compacts for hot forging demonstrated the feasibility of producing α-Fe of grain size 1 μm or less. The principal parameters determining the conditions of production of an ultrafine α-Fe grain are compact heating temperature and rate and duration of holding at the heating temperature. It is shown that ultrafine iron powders can be employed for manufacturing high-strength ultrafine-grained materials.
