Quantifying helium-bubble swelling in RAFM steels using TEM and the surface-step method
Nuclear Materials and EnergyIn fusion-relevant environments where transmutation helium accumulates, He bubble formation can become a critical damage mechanism in reduced-activation ferritic/martensitic (RAFM) steels because it drives swelling and can degrade mechanical performance.

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 ...

Spinning-Up the Envelope Before Entering a Common Envelope Phase
, 2010 We calculate the orbital evolution of binary systems where the primary star is an evolved red giant branch (RGB) star, while the secondary star is a low-mass main sequence (MS) star or a brown dwarf.
