本文示例介绍了位置灵敏原子探针在材料研究中的应用,其中包括有马氏体时效钢的时效初期反应,双相不锈钢内铁素体的调幅分解;铝合金内的细小析出物形成;Ⅲ—Ⅴ族化合物半导体的不均匀结构;及陶瓷氧化物超导体的表面偏聚。位置灵敏原子探针技术将位置灵敏探测器与飞行时间质谱结合起来进行微观分析,采用它可以在三维空间重构原子级化学组成。本文的示例将具体显示这种分析方法的作用。作者曾在本刊上撰文介绍一种国外最新研制成功的位置灵敏原子探针,并简要介绍了它在材料研究中的应用。本文将继续介绍位置灵敏原子探针的应用情况,以便读者了解到更新的动态,也更增强对位置灵敏原子探针的认识。
In this paper, we introduce the application of position-sensitive atom probe in material research, including the initial aging reaction of martensite-aged steel, the amplitude modulation decomposition of ferrite in duplex stainless steel, the formation of fine precipitates in aluminum alloy, -V group compound semiconductors; and surface segregation of ceramic oxide superconductors. Position-sensitive atomic probe technology combines position-sensitive detectors with time of flight mass spectrometry for microscopic analysis, using it to reconstruct atomic-level chemical compositions in three-dimensional space. The examples in this article will show in detail how this method of analysis works. The author has written in this article describes a newly developed foreign position-sensitive atomic probe, and briefly describes its application in materials research. This article will continue to introduce the application of position-sensitive atomic probes so that readers will learn about newer dynamics and enhance their understanding of position-sensitive atomic probes.
