根据 Staron、Jamnig、Leitner、Ebner 和 Clemens 的论文 [J.应用。水晶。 (2003), 36, 415–419]，提出以下几点。马氏体时效钢中沉淀过程的表征很困难，主要是因为形成的沉淀物是纳米级的。沉淀物类型的识别很复杂，因为即使沉淀物类型保持不变，其成分也会在老化过程中发生变化。对实验结果的解释应谨慎对待，特别是在使用间接方法（例如小角中子散射（SANS））时。原子探针场离子显微镜（APFIM）已被证明能够确定马氏体时效钢中细小析出物的类型和成分。简要讨论了 SANS 和 APFIM 的优缺点。
Further to the paper by Staron, Jamnig, Leitner, Ebner & Clemens [J. Appl. Cryst. (2003), 36, 415–419], the following points are made. Characterization of the precipitation process in maraging steels is difficult, primarily because the precipitates formed are on the nanometre scale. Identification of the precipitate type is complicated by the fact that its composition evolves during ageing, even when the precipitate type remains unchanged. Interpretation of experimental results should be treated with caution, especially when indirect methods, such as small-angle neutron scattering (SANS), are used. Atom-probe field ion microscopy (APFIM) has proved to be capable of determining the type and composition of the fine precipitates in maraging steels. The advantages and disadvantages of SANS and APFIM are briefly discussed.
