Abstract:

Recent experiments on the role of phase transformations on magnetization revealed a strong response of the magnetic remanence to small, subtle transformation effects during thermal cycling. The results suggest that magnetic remanence can serve as a unique thermal analysis method for steels. One of the potential applications is to determine the thermal history of components. The present report describes the results of magnetic remanence thermal analysis on a specimen from the muzzle end of a Bushmaster barrel which, according to video recording of test firing, experienced excessive heating during testing.
