| Abstract: | According to GB/T 15616-2008Quantitative Method for Electron Prohe Microanalysis of Metals and Alloys,the quantitative results of Si content in some W600 silicon steel was measured hy EPMA-WDS.The uncertainty components which might affect the measurement results were considered,calculated and synthesized. Finally the uncertainty result for the quantitative value of Si content in the silicon steel was got.The mass content of Si was 1.50%,and expanded uncertainty U=0.20%under the condition of coverage factor ... |
