Abstract

This paper presents an algorithm for the calculation of the coefficient (index) of friction at compression of the ring in hot deformation. The calculation considered the temperature-speed parameters of hot deformation: temperature of the workpiece, temperature of dies, the thermophysical properties of material of a workpiece and a die, parameters of equipment. Calculated curves for μ = μ (r). The authors give the comparative results of calculations and experiments on compression of ring samples in hot conditions.
