Abstract:
In this paper we demonstrate the first trial to perform steel health monitoring inside the steel grain, by comparing the misorientation of the Kikuchi lines with magnetic properties, namely the Barkhausen noise (BHN), differential magnetic permeability and coercivity. The results illustrate monotonic dependence of the magnetic properties on the crystalline misorientation. Apart from that, micro-hardness results have also been realized, illustrating a monotonic dependence on magnetic properties. Such dependence allows for the monotonic correlation of magnetic properties on mechanical properties and residual stresses and their corresponding use for industrial applications towards steel health monitoring.
