激光光谱的显微分析被广泛地用来研究合金中熔析的不均匀性和分析两金属交界区的金属互化物的成分。研究金属和合金中碳的分布是特别有意义的。本文主要讨论用激光显微分析法,对铬镍钼钒高合金钢 10X19H11M4φ的含碳量作定量分析,并研究这种钢的碳沿其焊缝截面 Microscopic analysis of laser spectra is widely used to study the inhomogeneity of the melt in the alloy and to analyze the composition of the intermetallics in the two metal junction regions. It is of particular interest to study the distribution of carbon in metals and alloys. This article focuses on the use of laser microscopic analysis of chromium-nickel-molybdenum-vanadium high-alloy steel 10X19H11M4φ quantitative analysis of carbon content and carbon steel along the weld section
