Analysis of Short - Range order Diffuse Scattering by High Resolution Electron Microscopy and the Image Processing System |
| Abstract |
The combined use of high resolution transmission electron microscopy and the image processing are applied to determine the atomic-scale structure of the short-range order diffuse scattering, Microdomain was not detected in quenched Ni₄Mo alloy which showed the diffuse scattering at {11/20} positions. The lattice modulation observed in this alloy seems to be attributed to the concentration waves appeared parallel to the {210} planes. In quenched Cu₃Pt alloy which showed the diffuse scatterings with twofold and fourfold splittings of intensity maxima, the L1₂- type microdomains were recognized. This microdomains were believed to have out-of-step relation between neighbors. |
