Superconducting quantum interference device (SQUID) was used for the detection of thermal aging of duplex stainless steels. It was found that the SQUID output signal pattern in the presence of AC magnetic field applied to the specimen was sensitive to the material property changes due to thermal aging at the operating temperature of light water reactors. Besides, the change in the SQUID output was more significant as the unaged specimens had more ferrite content.
