| Abstract: | The influence of overloading on HIC process of 42 CrMo steel / 1N H2SO4 systcm was stidicd by using a weight loaded testing machine, Experimental result showed that mostly overloading would make the fracture life of the specimen shorten. However, if the overloading was applied at the early stage of the service, the life time would be longer than that of un-overloadcd ones. The result was discussed according to the effect of loading history of hydrogen distribution. |
