Effect of Surface Cooling on Fatigue Life Improvement
No full textIn this study, we investigate the influence of surface cooling on the life of specimens undergoing low-to-intermediate-cycle fatigue. The experiments involve rotating-bending tests with Stainless Steel 304L and Steel 4145 specimens. External cooling air is provided via a vortex tube at a constant supply rate. Results are compared with the case of fatigue at room temperature. The results of experiments reveal significant improvement in fatigue life when the surface of the specimen is cooled. A possible explanation for the observed phenomenon is the notion of self-organization within the context of irreversible thermodynamics. © 2013 ASM International
