THE APPLICATION OF FIELD ION MICROSCOPE ATOM PROBE FOR MATERIALS SCIENCE
场离子显微镜原子探针在材料科学中的应用

The purpose of the present work is to introduce the principlesof field ion microscope-atom probe(FIM-AP)and the results of application tostudy the microstructure of materials.It includes the interaction between hydro-gen and the surface of refractory metal,the absorption and diffusion of hyd-rogen in the austenitic stainless steel,the observation of crystal boundary inthe doped tungsten wires,the short range order of Mo-W alloy and the stud-ies of precipitate phase in the magnetic materials.
