尽管纳米结构材料具有令人感兴趣的性质，但由于制备成本和可合成材料的范围有限，因此其用途有限。已经表明，这些限制中的大多数可以通过使材料经受大规模变形来克服，如在普通机加工操作期间发生的那样。车床加工过程中产生的各种纯金属，钢和其他合金的芯片被证明是纳米结构的晶粒（晶体）尺寸在100和800纳米之间。芯片的硬度被发现是显着大于散装材料。
In spite of their interesting properties, nanostructured materials have found limited uses because of the cost of preparation and the limited range of materials that can be synthesized. It has been shown that most of these limitations can be overcome by subjecting a material to large-scale deformation, as occurs during common machining operations. The chips produced during lathe machining of a variety of pure metals, steels, and other alloys are shown to be nanostructured with grain (crystal) sizes between 100 and 800 nm. The hardness of the chips is found to be significantly greater than that of the bulk material.
