Abstract Scope |
It is well known that hydrogen gas environment accelerates fatigue crack growth in the majority of steels. The degree of acceleration is influenced by various factors such as gas pressure, temperature, loading rate, material type, material’s strength and microstructure. These factors should adequately be taken into account in the strength design of hydrogen components, however, each factor has not been well understood with its influencing mechanism. In the presentation, some important experimental results are introduced with the results of microscopic observation of crack and fracture surface, and then the mechanisms are discussed. |
