Abstract

Segregation monitoring plays a crucial role in the quality control of steels, and elemental microanalysis using laser-induced breakdown spectroscopy (LIBS) can be employed as an approach in this process. In this study, we established a LIBS system utilizing a 9-ps pulsed laser operating at 355 nm and 35 Hz repetition to investigate steel segregation. Successful analysis of Aluminum (Al), Copper (Cu), and Manganese (Mn) segregation in steels was achieved. The LIBS mappings with a spatial resolution of 2 μm demonstrated agreement with results obtained from Electron Probe Microanalysis (EPMA), thereby affirming their reliability. Furthermore, by employing an even higher spatial resolution of 1 μm, fine results could still be acquired through LIBS on a steel area of 100 μm². These findings demonstrate the effectiveness of ps-LIBS for resolving elemental segregation and suggest its potential as an alternative tool for steel inspection.

基于皮秒激光诱导击穿光谱成像的钢材样品偏析高分辨率显微分析

偏析监测在钢材的质量控制中起着至关重要的作用，而利用激光诱导击穿光谱（LIBS）进行元素微量分析可作为这一过程中的一种方法。在这项研究中，我们建立了一套激光诱导击穿光谱系统，利用波长为 355 nm、重复频率为 35 Hz 的 9 ps 脉冲激光来研究钢材偏析。我们成功地分析了钢中的铝（Al）、铜（Cu）和锰（Mn）偏析。空间分辨率为 2 μm 的 LIBS 映像分析结果与电子探针显微分析 (EPMA) 得出的结果一致，从而证实了其可靠性。此外，通过使用更高的空间分辨率（1 μm），在 100 μm2 的钢面积上仍能通过 LIBS 获得精细结果。这些研究结果证明了 ps-LIBS 分辨元素偏析的有效性，并表明其作为钢检测替代工具的潜力。
