摘要
Typical nanocrystalline Fe<sub>73.5</sub>Cu<sub>1</sub>Nb<sub>3</sub>Si<sub>13.5</sub>B<sub>9</sub> and Fe<sub>73.1</sub>Cu<sub>1.2</sub>Nb<sub>12.5</sub>Si<sub>12.5</sub>B<sub>10</sub> alloys containmore expensive element Nb and their as-quenched amorphous ribbons are brittle. Partlyreplacing Nb by much cheaper V, we have developed a new-type Fe<sub>727</sub>Cu<sub>0.8</sub>Nb<sub>2</sub>V<sub>2</sub>Si<sub>13.5</sub>B<sub>9</sub>
