Method of Determining the Main Features of Magnetic Ferromagnetic Materials

Abstract

The purpose of this paper is to present a method for determining the main magnetic features such as magnetic induction B, magnetization M, the coercive magnetic field Hc, permeability μ, using hysteresis cycle chart.
The method can be used for:
- determining the amounts of phase with the existing magnetic properties of ferrous alloys,
- determination of delta ferrite in austenitic steels and the weld seam weld bonding of these steels,
- pointing to the deformation of martensitic transformation in cold austenitic stainless steels and proper calibration, intensity estimation of martensitic transformation and the amount of martensite in the structure.
