Effect of Rare Earth Additions on Hydrogen Embrittlement Cracking in 4340 Steel

The effect of a 0.2 weight percent cerium addition on the hydrogen embrittlement cracking resistance of AISI 4340 steel was investigated at yield strength levels of approximately 210 and 185 ksi (1450 and 1280 MPa). Sustained-load delayed failure data for precracked compact tension specimens electro...
