Abstract
A model is presented for magnetoacoustic emission (MAE) and magnetic Barkhausen emission (HBN) during incipient creep damage stages in Cr–Mo steel. The model qualitatively reproduces the peak in HBN intensity as one goes through the early incipient stages, and also qualitatively reproduces the strong decrease in MAE intensity through all the incipient stages, leading to over a 50% decrease.
