Abstract :
The electromagnetic characterization of dual phase stainless steel (SS2205) containing ferrite and austenite phase has been carried out by a magnetic NDE device MagStar. The efficiency of device has been demonstrated by generating different volume fraction of phases by suitable heat-treatment of the steel. A good correlation has been found between the magnetic and microstructural parameters of heat treated SS2205 steel samples. The magnetic flux density and r.m.s. voltage of magnetic Barkhausen emissions of heat treated steel increase linearly with ferrite percentage.
