摘要
We study the influence of gaseous hydrogen on the mechanical properties of hardened and deformed specimens of 07Kh13G20AN4 and 03Kh13N9G19AM2 steels under a pressure of 35 MPa in the temperature range 293-773 K. We establish that hydrogen causes the strain martensite transformation of nitrogen-containing austenite stable in air. Formation of a polygonal dislocation substructure by means of preliminary mechanical or thermomechanical treatment significantly decreases the tendency of steels toward hydrogen degradation. © 2000 Kluwer Academic/Plenum Publishers.
