Effect of Annealing Temperature on Magnetic Aftereffect and Positron Lifetime in Fe73.5Cu1Nb3Si13.5B9 Alloy
|
Abstract:
The magnetic aftereffect (MAE) and the positron lifetime were measured at room temperature on the Fe73.5Cu1Nb3Si13.5B9 alloy in as-cast and after annealing at temperature Ta in the range from 450 to 750℃. It was found that both the MAE and the positron lifetime decrease with increasing Ta when Ta≤600℃. While Ta≥650℃, MAE is essentially suppressed, and two positron lifetimes appear.
