The investigation of hydrogen effect on the mechanical properties of Incoloy 907, a Fe—Ni—Co superalloy, was made from ambient to cryogenic temperature (77 K) with and without hydrogen charging under different aging treatments. It was found that there exists an obvious IHE tendency in Inco 907 from ambient to cryogenic temperature, which is affected by the microstructure of the alloy. From ambient to LN temperature an obvious maximum of IHE susceptibility in the alloy was found at the temperature of —50°C for all the aging treatments. The occurance of the hydrogen embrittlement in Inco 907 and its temperature dependence can be well explained by the interaction between the hydrogen and the dislocation in the alloy
