Influence of an electric current impulse on the mechanical characteristics of 03Kh13N9G19AM2 stabilized austenitic steel in static tension under low temperature (down to 4.2 �K) conditions

Abstract

1. The amount of the jump in stress caused by the passage of a single electric current impulse through a sample of 03Kh13N9G19AM2 steel increases with a drop in test temperature and at 4.2 ° is 26% of the yield strength of the steel at the same temperature. 2. The tensile strength of samples subjected to current action is less by 50 kgf/mm2 at 77 °K than, less by 31 kgf/mm2 at 4.2 °K than, and equal at 293 °K to the tensile strength of samples tested without the influence of current.
