Figure 14. Fatigue resistance of MPEAs prepared by laser-based techniques: (A) S-N curves of SLM-CoCrFeMnNi[117]. (B) Evolution of the yield stress at an offset strain of 0.01% after cyclic loading at different temperatures and strain rates of SLM-CoCrFeMnNi[135]. High-cycle fatigue of SLM-CoCrFeNi: (C) S-N curve with the specimens used for the post-mortem examination indicated by the square box; (D) A plot of the measured maximum strain vs. fatigue cycles for the specimen tested under the maximum stress of σmax= 450 MPa with a fatigue life of Nf = 1.06 × 105[136].
