Basics of the new multiscale methodology 3D of mechanical properties prediction at extra-high temperatures

Marcin Hojny

Abstrakt

The paper presents example results leading to develop multiscale 3D methodology of mechanical properties prediction for steel deformed in the temperature range close to solidus line. Conducted experiments and simulations confirms the need to seek new methods to obtain precise characteristics in the context of detailed computer simulations.
