摘要

The development of some mechanic engineering systems in, feasible to pressure vessels, aeronautics, ship building technology, requires a full investigation of the material features that are to be examined under a low cycles fatigue to strains close to the limit of the material elasticity. In this paper some results concerning the evolution of inner second order tensions, microhardness in superficial layer during low cycles fatigue process and the microscopic images of cracks are presented. The studies are performed on two steels used in pressure vessel engineering. Using laminate samples, the investigations have been realized at variable solicitations of pure bending on a patented machine. A relationship between mentioned sizes is evinced and can be used in establishment of damage mechanism in fatigue process.
