Abstract

This study illustrates the sensitivity of Barkhausen noise and eddy current based sensors to monitor the evolution of micromagnetic properties during phase transformation due to plastic deformation of metastable austenitic steel AISI 304L. The phase transformation was carried out on flow formed tubes, under specific thermomechanical conditions to produce local graded areas. The results show a very good potential of both types of sensors to monitor the evolution of magnetic properties during the production process in order to use those signals in closed-loop property-control systems.
