Qx. Ba et al., Effect of annealing temperature on magnetic aftereffect and positron lifetime in Fe73.5Cu1Nb3Si13.5B9 alloy, J MAT SCI T, 16(4), 2000, pp. 447-448
The magnetic aftereffect (MAE) and the positron lifetime were measured at r
oom temperature on the Fe73.5Cu1Nb3Si13.5B9 alloy in as-cast and after anne
aling at temperature T-a in the range from 450 to 750 degrees C. It was fou
nd that both the MAE and the positron lifetime decrease with increasing T-a
when T-a less than or equal to 600 degrees C. While T-a greater than or eq
ual to 650 degrees C, MAE is essentially suppressed, and two positron lifet
imes appear.
