Abstract
The microstructure of 316L austenite stainless steel after charging with deuterium and tritium for 6 years at room temperature is studied. The results indicate that the morphology of fracture surface after blasting is ductile rupture with dimple, stress produced by blasting of high pressure leads to the martensite transformation. The deuterium and tritium improve the ε martensite transformation of austenite and reduce the fault energy,which reduce the hydrogen-resistant properties of 316L stainless steel.
