Effect of primary α-Fe on soft magnetic properties of FeCuNbSiB amorphous/nanocrystalline alloy

The effect of primary α-Fe precipitation on thermal properties and magnetic properties was systematically investigated by fabricating Fe76.5-xCu1NbxSi13.5B9 (x=0, 1, 2 and 3) amorphous/nanocrystalline ribbons using melt-spinning method at different cool rate, which is controlled by wheel linear speed. It was found that the rapid quenching process shows similar influence on α-Fe precipitation to heat treatment. The as-spun...
