“…Liu et al 28,29 demonstrated that the Basquin equation is well-fitted by the steel-alloy fatigue data in the ITF test. Similar findings have been reported by Wiriyasaroj et al 30,31 about steel, as well as on Ni-alloys, 32 Ti-Al alloys, 33 and copper alloys. 34 The Basquin equation was established for RT based on statistical data and the behavior of fatigue in all metals; nevertheless, the applicability of this equation at high temperatures is debatable.…”

“…It has been demonstrated by Balasubramanian et al 32 that the fatigue properties of AM'd Inconel 718 are lower than those of wrought ones, but after post‐processing, the fatigue behavior became a little closer to wrought ones. The comparison diagram of the various types of manufactured Inconel 718 has been shown in Figure 6.…”

The cumulative effect of many incidents that are brought about by an increase in temperature establishes an environment in which premature failure (including fatigue failure) becomes a challenging issue. Isothermal rotating bending fatigue (IT‐RBF) testing may simulate industrial components' high temperatures and rotating environments. This state‐of‐the‐art review paper covers the current research on IT‐RBF failure in wrought and additive‐manufactured alloys, focusing on microstructural and lifetime models. The article emphasizes the need of using microstructural information in fatigue life models to better represent complex material structure‐failure behavior associations. Additive‐manufactured alloys contain unique microstructural characteristics and processing‐induced defects making fatigue modeling difficult. The paper concludes with implications for industrial fatigue‐resistant alloy development. It emphasizes the necessity for a multidisciplinary approach that integrates materials science, mechanics, and data science to optimize these materials under cyclic loads. The review concludes by proposing future research and innovation in this subject.
