Tritium autoradiography was employed for the identification of: 1. the hydrogen distribution in irons with different purities; 2. the diffusion behavior uof hydrogen in metal under local load for different stress stand; 3. the distribution of tritium in the W alloys, 95%W-3.5%Ni-1.5%Fe, a kind of two-phase alloys consisted from W particles and binder of solution 54.2%Ni-27.1%Fe-20.5%W with high specific gravity and 4. the hydrogen distribution of different zones for the weld joint. It was found that the hydrogen distribution of iron is dependent on the purity of iron and the hydrogen solubility in the iron, however, grain boundary of high purity iron cannot be provided preferred sites for hydrogen accumulation site, but grain orientation difference is sensitive for tritium tracer. Tritium redistribution of hydrogen in different purity iron under different plastic deformation by the stress induced hydrogen segregation on the iron. Tritium distribution on the W-Ni-Fe sintcring alloys, even without etching, it is primarily accumulated on the interface of binding phase, which is dependent on relative solubility in two-phase alloys. The distribution of tritium on the different zone of the weld joint shows that hydrogen in the austenite weld, fusion zone. Overheat affected zone of matrix and matrix is different, which is closely connection of the carbon segregation of weld process and structure defect of matrix.

Four-point-bend specimens of 30CrMnSiA steel have been employed to investigate (Ⅰ+Ⅲ) mixed-mode hydrogen induced cracking (HIC) with hydrogen continuously charging in 1NH_2SO_4 solution. The experimental results showed that the different specimens exhibited almost the sams HIC susceptibility with KⅢ/ K_Ⅰ ratios ranging from 0 to 1.73. In the light of different characteristics of hydrogen accumulation due to hydrostatic stress gradient and plastic deformation above experimental results were discussed.
