Conclusions

  1. 1.

    The magnitude of the decrease of permeability with time for samples annealed in vacuum increases with increasing temperature and the level of the magnetic characteristics.

  2. 2.

    The value of the decrease of the permeability with time for samples annealed in hydrogen is much less than for samples annealed in vacuum at the same level of magnetic characteristics.

  3. 3.

    The magnitude of the decrease of magnetic permeability with time in weak fields at a given induction is determined apparently by the concentration of carbon in the steel; it is small in unannealed steel and in the steel annealed in hydrogen and is not related to the level of the magnetic characteristics.
