N2 - Magnetic Incremental Permeability (MIP) being highly stress dependent proves to be very effective to evaluate materials non-destructively. In this article, modelling technique based on Jiles-Atherton model has been proposed to simulate the signature MIP butterfly loop for the 12 Cr-Mo-V-W creep test samples. Jiles-Atherton parameters imply physical interpretations. From these butterfly loops, a physical relation, based on the values of the J-A's parameters, with the microstructure such as precipitations, dislocations, Kernel Average Misorientation (KAM) has been investigated with experimental as well as simulation validations. It is especially observed that J-A's parameters are well correlated to the precipitation quantity and KAM.
