Effect of forging on ferromagnetic properties of low-carbon steel

Abstract

Mechanical work usually has adverse effect on magnetic properties of soft magnetic materials. It reduces saturation magnetic flux density, decreases drastically magnetic permeability, widens hysteresis loop and decreases magnetostriction coefficient which leads to less strain under certain magnetic field intensity. This paper presents a practical way to improve magnetic properties of low-carbon steel, which had already been deformed by forge technique.
