本文证明三维原子探针（3DAP）能够表征镁合金中的纳米析出相。结合应用3DAP和透射电子显微镜显示，在Mg-2.4wt.% RE-0.4wt.% Zn-0.6wt.% Zr合金具有有序的G. P.区结构和约3.2at.%的组成Nd，1.0原子% Ce和1.2原子% Zn.
This paper demonstrates that the three-dimensional atom probe (3DAP) is capable of characterizing nanoscale precipitates in magnesium alloys. Combined application of 3DAP and transmission electron microscopy reveals that the major precipitate phase in a Mg–2.4wt.%RE–0.4wt.%Zn–0.6wt.%Zr alloy has an ordered G.P. zone structure and a composition of approximately 3.2 at.% Nd, 1.0 at.% Ce and 1.2 at.% Zn.
