Rheological behavior of superplastic nanocrystalline and amorphous materials

摘要

Demonstrating structural superplasticity as compared with crystallized metallic melts and amorphous materials, rheological behavior of metallic and ceramic materials is analyzed. The rheological state of the materials varies from tough to tough-plastic one. Superplasticity at high deformation rates and low values of shear viscosity being peculiar to the materials is considered as enough prospecting for development of new metal forming processes.
