The effects of cyclic heating and cooling on the mechanical properties of various steels at 550, 700, and 850 deg C were studied. With cyclic heating above 78O deg C and cooling, the strength of the steel dropped with the increase of carbon. The strength of the material was impaired by microcracks formed on the surface. In the alloy EI437 the cracks appear exclusively on the grain boundaries while in the rest of the materials they appeared along the grain itself. (R.V.J.)
