Abstract

Deformation of an amorphous cobalt alloy of strip configuration in creep tests in a variable temperature field is studied. An analytical form of the creep curve is found, and a prediction calculation of the resistivity by means of the proposed creep function is carried out. The physical meaning of the parameters of the creep equation is established, and their dimensionality is found. It is shown that, under the action of a variable temperature field, the creep of the alloy is not Newtonian and the material under strain exhibits pseudoplastic properties. It was found that, in the absence of heating, the viscosity of amorphous strip alloys can be considered within the Bingham plastic model.
