纳米多晶材料,可以看作是在结构上不同于晶体或玻璃的一类新的固态物质。构成纳米多晶材料的各个晶体的尺寸为几个纳米(1～10nm)的数量级。这类微晶材料之所以令人特别感兴趣,主要是由于它们的
Nanocrystalline materials, can be seen as structurally different from the crystal or glass of a new class of solid material. The size of individual crystals that make up the nano-polycrystalline material is on the order of a few nanometers (1 to 10 nm). The reason why such microcrystalline materials are of particular interest is mainly due to them
