Abstract
Abstract—The structure of a high-temperature nickel alloy subjected to hot plastic deformation has been studied by optical metallography and scanning electron microscopy. The compression-test results obtained in the strain-rate range from 10–3 to 10 s–1 and temperature range of 900–1140°C have been used to construct a processing map showing extreme values of the coefficient of efficiency of the mechanical energy dissipation. A correspondence between the positions of extrema on the processing map and the peculiarities of structural changes has been found.
