结论非晶态合金中纳米晶相的存在有时会对合金的耐蚀性产生很大的影响。这些影响是不利的还是有利的，取决于纳米晶相的尺寸、组成和稳定性。一般来说，直径小于20 nm的析出物不会产生很大的影响，只要基体中含有足够多的与耐蚀性有关的元素，如铬。
ConclusionsExistence of nanocrystalline phases in amorphous alloys some times gives large effects to corrosion resistance of the alloy. The effects are detrimental or favorable depending on the size, composition and stability of the nanocrystalline phases. In general, precipitates less than 20 nm in diameter do not give large effect as far as the matrix contains enough amount of elements such as Cr which is responsible to the corrosion resistance.
