Following the first experimental results concerning the possibility to estimate the fatigue limit by semi-static tensile traction test, the authors are continuing the experimental thermo-analysis of the curve zone between the origin and the yield stress; that is rich of indication about the fatigue failure process. The tests carried out on the AISI 304 steel by thermal analysis, confirmed the good approximation between the values of the fatigue limit estimated by fatigue test and by the quasi-static test. The results shoed the importance of the thermo-analysis of the part of the stress-strain curve (distant from the yield point) where only in macroscopic terms the behavior is perfectly elastic.
