【 摘 要 】

Annotation. Technological aspects of using the effect of superplasticity in the manufacture of many mechanical engineering products by pressure treatment methods are considered. Superplasticity, which manifests itself under special conditions, allows the formation of complex forms of specific materials with heat and deformation resistance, hardness and brittleness, and atypical physical and technical properties at low costs. The conditions and factors of the manifestation of superplasticity effect for traditional and innovative materials, such as metallic glass and nanoceramics, are revealed. New mold forming technologies that do not require press equipment are considered, and the areas of optimal use of the capabilities of the superplastic state of materials are specified.
