Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    A. flow-type apparatus has been developed for the investigation or processes of heat treatment of powered materials in moving vibrating beds.

  2. 2.

    A study was made of the final reduction of residual oxides in an iron powder and milled sponge iron and hydrogen. It was established that: a) at a temperature above 700° C a high-quality product (total Fe≃99.0%) can be obtained, with apparatus throughputs of 45 and 30 g/min, respectively, by annealing PZh5M iron powder for 4–5 min and milled sponge iron 8–10 min, b) the final reduction of residual oxides is controlled by diffusion mass tranport.
