Strength and crack resistance of chromium-nickel-manganese 03Kh19AG3N10 steel in the temperature range 293-4.2 K

We present the results of the experimental investigation of the characteristics of strength and crack resistance of chromium-nickel-manganese 03Kh19AG3N10 steel in the temperature range 293–4.2 K under static (in the initial state and under the action of pulses of electric current) and dynamic loads...

Description
Summary:We present the results of the experimental investigation of the characteristics of strength and crack resistance of chromium-nickel-manganese 03Kh19AG3N10 steel in the temperature range 293–4.2 K under static (in the initial state and under the action of pulses of electric current) and dynamic loads. We consider some distinctive features of the process of the discontinuous yield of steel at a temperature of 4.2 K and its influence on the kinetics of fracture processes. The comparative analysis of temperature dependences of the characteristics of strength, plasticity, and crack resistance of 03Kh20N16AG6, 03Kh20N16AG6Sh, and 07Kh13N4AG20 steels extensively used in cryogenic engineering and 03Kh19AG3N10 steel demonstrates that 03Kh19AG3N10 steel can be used in the temperature range 293–4.2 K.
