Abstract
In this work the magnetic properties of AISI 304L austenitic stainless steel was subjected by using the magnetic induction with different working frequencies. For this purpose a sheet rolled from 10 to 80 % reduction at 0ᵒC was used. Then, by using Eddy current instrument at frequencies from 50 to 10000 Hz, magnetic behavior was studied. The results were made of two parts: (1) linear part where the reduction was lower than 10%, more non-magnetic transformation (Ɣ→ɛ) occurs in this region, (2) Exponential Rise to Max curve where the sudden increase in formation of ά-martensite (Ɣ→ά) and disappearing of ɛ-martensite occurs, lead to a sharp increase in permeability. Also an obvious relation between parameters of the function that fitted with it and structural changes was found.
