Application of thermal analysis technique for development of technology of melt preparation to obtain “thick” amorphous Co-alloy microwires

The thermal analysis technique of estimating the ability of a melt to overcool is used to determine the optimum technological regimes of melt preparation in all the production stages of amorphous wires. The temperature range of high-temperature melt homogenization and the regimes of precursor extrac...

Summary:The thermal analysis technique of estimating the ability of a melt to overcool is used to determine the optimum technological regimes of melt preparation in all the production stages of amorphous wires. The temperature range of high-temperature melt homogenization and the regimes of precursor extraction and melting are defined for the model Co 69 Fe 4 Cr 4 Si 12 B 11 alloy. With use of the established regimes of heat treatment, the precursor melting is conducted and the samples of high-ductile amorphous microwires with a diameter 200 μm are produced by the Ulitovsky–Taylor method.
