Conclusions

  1. 1.

    A study was made of the magnetic properties of specimens from an iron-silicon powder prepared by the method of impregnation from point sources.

     
  2. 2.

    Using this process, it is possible to produce, at relatively low temperatures (800–1000°C) and short treatment durations (3–4 h), homogeneous alloy powders in which the silicon is present in the form of anα solid solution.

     
  3. 3.

    It is shown that the magnetic properties of the material investigated depend to a large extent upon its porosity and the sintering conditions employed. Maximum magnetic properties are exhibited by specimens with a coarse-grained structure and pure grain boundaries.

     
  4. 4.

    Prealloyed iron-silicon powder may be recommended for the production of sintered soft magnetic parts operating in constant and commercial-frequency (50 Hz) alternating fields.
