在本报告中，我们提供了一个框架，用于描述奥氏体不锈钢中氢及其同位素在氢存储和分配基础设施工程感兴趣的温度和高气压下的渗透性、溶解度和扩散率。我们证明了使用真实气体行为来模拟这些条件下氢气渗透和溶解的重要性。一个简单的单参数状态方程（阿贝尔-诺贝尔状态方程）可以捕获压力低于 200MPa、温度在 223 到 423 K 之间的氢气及其同位素的真实气体行为。我们利用奥氏体不锈钢中氢传输的文献来提供测试程序的一般指导和澄清，并为适当的渗透率、扩散率和溶解度关系提供建议。 奥氏体不锈钢。描述了各种奥氏体不锈钢的氢气预充和浓度测量，并用于生成更准确的溶解度和扩散率关系。 (c) 2006 年国际氢能协会。
In this report, we provide a framework for describing the permeability, solubility and diffusivity of hydrogen and its isotopes in austenitic stainless steels at temperatures and high gas pressures of engineering interest for hydrogen storage and distribution infrastructure. We demonstrate the importance of using the real gas behavior for modeling permeation and dissolution of hydrogen under these conditions. A simple one-parameter equation of state (the Abel-Noble equation of state) is shown to capture the real gas behavior of hydrogen and its isotopes for pressures less than 200MPa and temperatures between 223 and 423 K. We use the literature on hydrogen transport in austenitic stainless steels to provide general guidance on and clarification of test procedures, and to provide recommendations for appropriate permeability, diffusivity and solubility relationships for austenitic stainless steels. Hydrogen precharging and concentration measurements for a variety of austenitic stainless steels are described and used to generate more accurate solubility and diffusivity relationships.
