Diffusion of Helium and Nucleation-growth of Helium-bubbles in Metallic Materials
-
摘要: 简述了金属材料中氦聚集行为的研究概况 ,特别是本课题组近年来对奥氏体不锈钢中氦扩散及氦泡形核生长机制的研究结果 ,并提出了这个领域有待解决的问题. Studies of diffusion and aggregation behaviour of helium in metallic materials are very important to solve the problem of helium embrittlement in structural materials used in the environment of nuclear power. Experimental studies on helium diffusion and aggregation in austenitic stainless steels in a wide temperature range have been performed in our research group and the main results obtained are briefly summarized. The mechanism of nucleation growth of helium bubbles has been...Abstract: Studies of diffusion and aggregation behaviour of helium in metallic materials are very important to solve the problem of helium embrittlement in structural materials used in the environment of nuclear power.
