| 中文摘要 | Conventional and high-resolution electron microscopies were used to investigate the microstructure and precipitation mechanism of four kinds of gamma'-Fe4N nitrides, formed at the surface during nitriding of polycrystalline pure iron sheet. gamma' nitrides in the top columnar compound layer were thin plates (3-12 nm), which precipitated from epsilon-Fe2-3N grains with orientation relationship of (1 (1) over bar1)gamma'//(0001)epsilon and [011]gamma'//[1 (2) over bar 10]epsilon. Those in the transition compound layer remained as equiaxed grains (1-1.5 mum), which grew from the alpha-Fe substrate during nitriding. In the diffusion layer, striated gamma' nitrides nucleated from alpha"-Fe16N2 nitrides with orientation relationship of (100)gamma'// (1 (1) over bar0)alpha" and [011]gamma'//[111]alpha", while unstriated gamma' nitrides precipitated from the alpha-Fe substrate with the orientation relationship of (100)gamma'//(1 (1) over bar0)alpha and [011]-gamma'//[111]alpha. |
