Abstract

The temperature – strain rate conditions of high-temperature structural superplasticity are determined for the 01420T alloy with the initial bimodal structure. The structural state of specimens of alloy 01420T, superplastically deformed to failure under the conditions of high-temperature structural superplasticity, is studied. It is revealed that in the working part of specimens of the alloy 01420T during the superplastic deformation fi brous structures forms as a result of the viscous fl ow. They are localized in grain boundary cavities and cracks. The probable causes of partial melting of the 01420T alloy and the mechanism of its superplastic deformation are analyzed.
