METHOD FOR TERMOMEcHANICal TREATMENT OF microwire WITH thread FROM AMORPHOUS ALLOY ON THE BASIS OF COBALT IN GLASS SHELL

摘要

The invention relates to nonferrous metallurgy, in particular to a method for termomechanical treatment of microwire with a thread from amorphous alloy on the basis of cobalt in the glass shell, which is used as low-coercitivity material in the form of amorphous or nanocrystalline microwire (MW) for supersensitive pickups, among high-frequency transformers, effective electromagnetic wave absorbing surfaces. A method for termomechanical treatment of microwire with a thread from amorphous alloy on the basis of cobalt in the glass shell, which involves heat treatment of the produced microwire according to the method by Ulitovskyi-Teilor at the temperature of 793-803 C for 1770-1830 s at the simultaneous deformation of the microwire by the single-axis stretching of 125-135 MPa. The invention provides for the receiving of microwire with high magnetically soft properties and increased thermal firmness and to increase duration of work of devices from MW in the high temperatures conditions of exploitation.
