The effect of oxygen contained in hydrogen gas environment as an impurity on hydrogen environment embrittlement (HEE) of A333 pipe steel was studied through the fracture toughness tests in hydrogen gases. The oxygen contents in the hydrogen gases were 100, 10, and 0.1 vppm. A significant reduction in the J‐Δa curve was observed in the hydrogen with 0.1‐vppm oxygen. Under given loading conditions, the embrittling effect of hydrogen was completely inhibited by 100 vppm of oxygen. In the case of the hydrogen with 10‐vppm oxygen, initially the embrittling effect of hydrogen was fully inhibited, and then subsequently appeared. It was confirmed that 1‐vppm oxygen reduced the embrittling effect of hydrogen. The results can be explained by the predictive model of HEE proposed by Somerday et al.

“…Van Paepegem et al [24] used bending fatigue rig for composite materials where fretting action can be considered between sample and fixed joint. Notable reviews and experiments were carried out on wear, fatigue [25][26][27][28][29][30][31][32][33][34][35][36][37][38] as well as fretting fatigue [23,[39][40][41][42][43][44][45][46][47][48][49] However, relatively less on bending accelerated fretting fatigue [22,[50][51][52]. Considering all above mentioned parameters with conditions, some perfect attributes [53] of fretting fatigue test rigs (FFTR) must have Versatility to various dimensions and stiffness of the samples and fretting pads; Possibility to perform different states of load (constant or alternating load); Scope to create fretting fatigue mechanism by recording the information from various tried materials that could be applied to different model to foresee the fatigue life; Accessibility to gauge fretting stresses and strains; Minimal cost of setup to perform a few tests at the same time; Flexibility of load recurrence.…”

Fretting fatigue has emerged as the center of interest for research in recent decades due to its high importance in real application field. Despite this advancement, comparatively few experiments as well as studies have been accomplished on bending fretting fatigue. Researchers either developed new test rigs or accepted a conventional concept since there exists no specific, standalone and standard test rig. However, as it is difficult to compare each work with others, the increasing number of test rigs are not suitable to ensure the justified results under conditional circumstance. This article classified the existing bending fretting fatigue test rigs depending on the variable parameters like fretting and loading actions. It can be mentioned that reciprocating fretting fatigue test rigs have more diversities as compared to rotary fretting fatigue test rigs due to the advantages of variable loading values, displacement controlling, fretting damage pre-determination and other desirable purposes. This article might be useful as a state of art for future contributions of the modern technology in industrial applications.

“…In the process of fretting wear, severe surface damage leads to formation of local stress concentration area where the initiation and propagation of fatigue cracks are located. In this regard, the fatigue strength of metallic materials is significantly reduced compared to that without fretting [17,18]. Therefore, it is of great importance to investigate how fretting wear affects fatigue behavior of structural component involving contact parts.…”
