Magnetic properties of sintered iron-silicon alloys

Conclusions
- 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.
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.
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.
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.
