Influence of Hydrogen on Age-Hardening Processes in 15-5 Precipitation Hardened Stainless Steel

Source

The aging characteristics of 15-5 precipitation hardened stainless steel were altered when age-hardening took place in a hydrogen environment. The presence of hydrogen increased the peak hardness and decreased the time to achieve peak hardness. Furthermore, the hardness of the hydrogen-aged samples increased to a maximum value with time of storage at room temperature. These observations are discussed in terms of proposed mechanisms for hydrogen embrittlement.
