Experimental study on fatigue growth of surface cracks on overlay of hydrogenation reactor
(0) The fatigue growth of surface cracks in the overlay significant influence the safety hydrogenation reactor. In this study a plat specimens with prefabricated surface crack on overlay were machined. Then the fatigue loading experiments were processed on the MTS-880 fatigue machine. The results showed that surface crack on stainless steel overlay would penetrate through the interface of weld overlay and base material, and growth into base material under the fatigue loading condition, when weld overlay and base material were combined with each other better. The fatigue propagation rate of surface crack on overlay was also given in the paper.
