Abstract
The article describes an experimental method for estimating the true flow stress at superplastic deformation. Studied changes of the true stress at superplastic deformation in optimally mode the precipitation-hardening alloy of cobalt-nickel-niobium. The microstructure of the alloy according to the extent of superplastic deformation
