抄録

Hydrogen embrittlement of steel has been investigated both by tensile test and internal friction technique.<BR>Hydrogen was charged in specimens by cathodically electric method and high temperature method. High temperature method charged hydrogen in the specimens at γ-phase (950°C) and trapped within by following water quenching. And immediately after chargings, specimens were aged at various time intervals and measured the change in notch-tensile-strength at each aging time by tensile test.<BR>Hydrogen cold-work-peak height was measured at various aging levels.<BR>N.T.S. of materials decreases with increasing aging time, goes through its minimum and recovers to the value of the hydrogen-free materials.<BR>Hydrogen cold-work-peak height increases with increasing aging time, goes through its maximum and peak vanishes by long enough aging.<BR>Parallelism was found between the drop in toughness and the hydrogen cold-work-peak height. Further, there exists a linear relatioship between the two.
