The use of coercive forces in the investigation of the process of pressing ferromagnetic powders

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

Summary

  1. 1.

    It is shown that the dependence of the coercive force on density in the range 2.75–7.25 g/cm3 has a distinct maximum.

  2. 2.

    It is found that the character of function Hc=f(d) sharply changes during short annealing.

  3. 3.

    A curve is plotted to show the dependence of the change of coercive force (†Hc) on density; it shows the presence of work hardening at various stages of pressing and its monotonie increase with increasing density,

  4. 4.

    It is shown that the use of coercive force in the investigation of the process of pressing can offer certain advantages.
