The influence of multicycle fatigue actions and thermal exposition, previously hardened in the rate of the air shot-blasting, on such characteristics of cylindrical samples made from alloys V95 and D16T as roughness and microhardness was researched. In fact, surface plastic hardening significantly affects the growth of microhardness in comparison with samples unhardened. Microhardness decreases to values corresponding to sample unhardened after thermal exposition. Surface hardening increases the roughness layer and further thermal exposition and fatigue tests have no effect on these parameters. Results of experimental measurements are presented in tables and graphs.
Keywords: cylindrical samples, alloys V95 and D16T, hardening, microhardness, roughness.
Mots-clés : multicycle fatigue actions, thermal exposition
