摘要
本文将场离子显微镜原子探针(FIM-AP)应用于材料微结构研究,包括氢与难熔金属表面相互作用及在奥氏体不锈钢中扩散、掺杂钨丝晶界观察、Mo 合金短程有序化及磁性材料沉淀相结构研究。讨论了 FIM-AP 在材料科学研究中应用的前景和存在问题。
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.
