INFLUENCE OF TEMPERATURE-RATE LOADING CONDITIONS ON SYSTEM OF MECHANICAL PROPERTIES OF CHROME-NICKEL STEELS

The purpose is the development of the equipment for complex studying high-strength structural steels to guarantee reliable predicting their service, as well as the investigation of the criteria of destruction of these materials in the temperature range from 4,2 to 300K under static and quasistatic loading conditions. Dislocation and thermal mechanisms of a step-wise plastic deformation at cryogenic temperature conditions, and variable loading rates have been proposed. Experimental data on the system of mechanical properties of high-strength structural materials at polymorphic transformation caused by a low-temperature plastic deformation has been obtained. The materials has been introduced in the cryomechanical laboratory in Design Bureau "Khimavtomatika" (Voronezh)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
