Mechanical, Electromagnetic, and Tribological Properties of Microspirals Made from Amorphous and Crystalline Metallic Materials

The mechanical properties of the wires made from the Co69Fe4Cr4Si12B11 amorphous alloy, tungsten, molybdenum, and 40KKhNM steel and the microspirals made from the wires and the electromagnetic and tribological properties of the amorphous alloy wires, which are prepared with protective sheaths made in the form of a microspiral from the selected materials, are studied. All the wires are found to have a high tensile strength (2100–3100 MPa). Elastic compression ability of the microspirals is found. The friction is shown to be minimal in the amorphous alloy–amorphous spiral pair. As for a combination of the properties, an amorphous spiral containing a stress-sensitive amorphous wire can be recommended as a working element of an electromagnetic transducer.
