Ion Irradiation Effect of Austenitic Steels and Ferritic-Martensitic Steels [PDF]
, 2015 奥氏体不锈钢被广泛地用于当前的商业沸水堆、压水堆和部分快堆的堆芯及其附属结构材料。铁素体-马氏体钢是高剂量反应堆结构候选材料，比如用于聚变堆的第一壁材料，以及快堆的燃料包壳及管道。与奥氏体不锈钢相比，铁素体-马氏体钢最明显的优势就是其较高的抗辐照肿胀能力。低活化铁素体-马氏体钢降低或消除了一些长衰变元素，降低了材料的活性，使其在相对短的时间内完成衰变，便于退役后浅埋废料。为了研究奥氏体钢和铁素体-马氏体钢的辐照性能，并探究辐照温度、注He浓度、辐照剂量等对其辐照效应的影响，本论文对奥氏体不锈钢304 ...

, 2013 为了研究异种材料焊缝的耐腐蚀性能, 对316L与304不锈钢进行了激光焊接。通过组织观察和XRD技术检测了母材及焊缝微区的组织结构, 采用动电位极化的方法测试了316L和304奥氏体不锈钢及其激光对接焊缝的耐腐蚀性能, 并分析了焊缝耐腐蚀性提高的原因。结果表明, 在室温3.5%NaCl溶液中, 焊缝及母材的腐蚀均以点腐蚀为主, 且点蚀基本在晶界处萌生, 焊缝的耐腐蚀性相对母材有了明显的提高;激光焊缝组织的晶粒尺寸较母材明显细化, 相成分以奥氏体为主, 有明显的择优生长取向, 且奥氏体含量相对母材有所增加,
