THE ANALYSIS OF THE RELATIONSHIP BETWEEN THE MAXIMUM DIFFERENTIAL AND THE MAXIMUM PERMEABILITY OF STEELS
(pp. 39-45)

Abstract. Due to the analytical and statistical analyses of the magnetic properties of magnetically soft and magnetically hard steels it is revealed that there is a strong correlation between their maximum differential magnetic permeability m_dm and maximum magnetic permeability m_m, which is close to a linear functional dependence. This dependence can be used in practice for estimation of m_dm from m_m and m_m from m_dm. It is shown that the ratio m_dm/m_m can be calculated using the developed formula for steels with a known coercive force, residual magnetization and magnetization of technical saturation.

Keywords: ferromagnetic steels, magnetic structural analysis, nondestructive testing, magnetic properties, maximum differential permeability.
