stress conditions of σ a = 50.8 MPa. Thus, the fatigue behavior under the lower stress conditions of σ a ≤ 40.9 MPa was considered the high cycle fatigue, whereas the fatigue behavior under σ a = 50.8 MPa was considered the low cycle fatigue. In the high cycle fatigue regime, σ a ≤ 40.9 MPa, the fatigue life at 200 °C was longer than that at RT. This may be unique to the lattice structure employed in this study.
