The technique proved to be a systematic and accurate ap- proach in producing visual images or maps of elemental distributions at cross-sectional surface of a stainless steel sheet. Two stain- less steel sheets served as research objects: 3 mm×l 300 mm hot-rolled stainless steel plate and 1 mm×l 260 mm cold-rolled plate. The cross-sectional surfaces of the two samples at 1/4 position along the width direction were scanned (raster area -44 mm2 and 11 mm2) with a focused laser beam (wavelength 213 nm, diameter of laser crater 100 μm, and laser power 1.6 mJ) in a laser abla- tion chamber. The laser ablation system was coupled to a quadrupole ICP-MS, which made the detection of ion intensities of 27A1+, 44Ca+, 47Ti-, 55Mn+ and 56Fe+ within an area of interest possible. One-dimensional (ID) content line distribution maps and two- dimensional (2D) contour maps for specific positions or areas were plotted to indicate the element distribution of a target area with high accuracy. Statistic method was used to analyze the acquired data by calculating median contents, maximum segregation, sta- tistic segregation and content-frequency distribution.展开更多
