Thermal Fatigue Behavior

Hot-working tools are frequently exposed to high cyclic temperature and mechanical loads, usually resulting in thermal fatigue cracking, which is observed as a network of fine cracks on the surface. The crack network degrades the performance of the tool and even invalidates it. Deep rolling is a surface strengthening treatment generally applied to improve the fatigue performance of metal components. But few attentions are paid on its influence on thermal fatigue cracking of the components, considering the relaxation of residual stresses and work hardening, which are deemed to mainly account for the improvement of fatigue performance. In this paper experiments were carried out to investigate the influence of deep rolling on thermal fatigue behavior of hot-work tool steel AISI H13. The experiment results show that deep rolling can improve the thermal fatigue behavior of AISI H13. To explore the mechanism of the effect, the changes of the residual stresses, the microhardness of the samples are also presented.

With the Uddeholm self-restricted thermal fatigue method, the transformation of phase constitutions and morphology of boride layer after 3000 cycles of thermal fatigue test was studied by XRD and SEM and the surface residual stress in the process of thermal fatigue test was researched by X-ray Stress Analyzer; the formation of the heat checking of boride layer was also analyzed. The results show that with the high strength and excellent thermal stability of boride layer, morphology of heat checking alters. Therefore, boronizing treatment of H13 steel improves its thermal fatigue behavior.
