After the medium-frequency magnetic pulse treating (frequency 1500-2000Hz, field intensity 200-250Oe) on amorphous Fe (Co)-M-B-Cu alloys, the vacuum anealing at low-temperature were in progress at 50°C-100°C for 30 min and 60 min. The soft magnetic properties of nanocrystalline alloy obtained by above mentioned treatments were measured by the vibrational specimen magnetometer. The results show that the structral relaxation , free volume migration and annihilation during the vacuum annealing will lead to the reduction of like-vacancy defects concentration and distortion stress. So the soft magnetic properties of nanocrystalline alloy will be improved further.

We Successfully Prepared the Rod Glassy Samples of (Fe1-xCox)76Si9B10P5 (x = 0~0.4) Bulk Metallic Glass (BMG) with the Diameters up to 3.0 mm by Substituting Fe for a Small Amount of Co Element. A Certain Amount of Co Substitution for Fe Contributes to the Increase of the Glass-Forming Ability (GFA) while Maintaining Good Mechanical Properties (the Fracture Strength up to 3700 MPa). This Co-Added Ferromagnetic Bulk Glassy Alloy System Also Exhibits a Higher Saturation Magnetization of 1.49 T and Lower Coercive Force (Hc, 1.2 A/m). The Fe-Based BMGs with Alloying a Small Amount of Co Element Demonstrate Excellent Combination of High GFA, Good Soft-Magnetic Properties as Well as High Strength.
