摘要：
The influence of helium and hydrogen on the mechanical properties of austenitic and martensitic steels is illustrated by reviewing some recent results mainly obtained by using the light ion simulation technique. They include: (a) A comparison of the creep rupture behaviour of implanted 316L, 1.4970 and 1.4914 steels at 873 K and a tentative explanation of the different embrittlement mechanisms which is based on microstructural information. (b) Some general features of helium embrittlement in fatigue and crack growth of 316L steel which can be deduced from the scarce experimental data in this area. (c) Some preliminary results on the effect of implanted hydrogen on tensile properties of 316L and 1.4914 steel at low temperatures.
