Structural and phase sensitivity of the maximum differential magnetic susceptibility of steel

详细

It is shown that the maximum differential magnetic permeability (μ_dm) and susceptibility (χ_dm) of steel are fully determined by its coercive force, remanent magnetization, and technical saturation magnetization. The sensitivity of χ_dm to the structure- and phase-sensitive parameters of a metal is analyzed. The problems of controlling metal manufacture conditions that can be solved by measuring χ_dm or μ_dm are determined.
