Summary

  1. 1.

    The course of the sintering process of the iron-silicon alloy with 6.5% Si was investigated over the temperature range 20–1200°C by the methods of electrical resistivity, shrinkage, bending strength, and coercive force measurement.

     
  2. 2.

    It was established that, at sintering (temperatures of up to 800°C, the density of specimens decreases.

     
  3. 3.

    It is shown that the formation of a solid solution of silicon in iron begins at temperatures of 700–800°C and is essentially completed at temperatures of 1150–1200°C.

     
  4. 4.

    To obtain optimum, stable properties, the iron-silicon alloy with 6.5% Si should be sintered at a temperature of 1150–1200°C (if the process is performed in a vacuum).
