| Abstract: | The brittle cracking hydrogenation device hydrogen mixing heat exchanger shell entrance over what happened in detail, including the analysis of visual inspection, chemical composition, microstructure, mechanical properties and fracture. The results show that, brittle crack is due to delayed crack caused by hydrogen welding.Through this article, can provide solution for the analysis of similar nozzle cracking phenomenon. |
