Effect of Steel Metallurgy on Its Magneto-Mechanical Behaviour in Weak Magnetic Fields

Abstract

The magneto-mechanical behaviour of five steels, mild steel, HSLA 80, HY 80, HY 100 and a quenched alloy steel, has been investigated. Magnetic fields of the order of the Earth's field and compressive stresses up to 200 MPa were applied to the steels. The increase in magnetization due to stress cycling in a constant applied field and to field cycling at constant stress was measured. The results show that the differential permeability of the steel largely determines the magnetization increase and that steels with similar microstructures have similar magneto-mechanical response. The strength or hardness of the steel is a less reliable indicator of magneto-mechanical response
