摘　　要：简要介绍了原子探针，特别是三维原子探针（３ Ｄ Ａ Ｐ） 的最新发展及其特点．３ Ｄ Ａ Ｐ 在探测到单个原子位置的同时能鉴别其种类，因而几乎能以原子分辨力显示出材料中大部分原子在实空间中的三维分布．文章举例说明了常规 Ａ Ｐ 和３ Ｄ Ａ ＰRecent progress in the development of atom probes, especially the three dimensional atom probe (3DAP) and their applications to interface studies of metallic materials is briefly reviewed. By employing a 3DAP it is possible to determine the position of a single atom and at the same time to identify its species. Thus 3DAP can map out elemental distribution in real space with almost atomic resolution. Unique features of the atom probe (AP) are demonstrated by describing recent applications of conventional atom probes and the 3DAP to interface chemical analysis of metallic materials.
