摘要： PROBLEM TO BE SOLVED: To provide a method for quickly performing quantitative analysis of an inclusion composition existing in a metal material by using a spark discharge type emission spectral analysis method.
SOLUTION: The method for measuring a nonmetal inclusion composition in a metal sample is characterized as follows. When a spark discharge is generated between the metal sample and a counter electrode and an inclusion existing in the metal sample is measured from the emission intensity of each element acquired therefrom, the intensity ratio determined by dividing an intensity value of an emission spectrum intensity line acquired in each spark discharge by the intensity of a matrix element is used, and the intensity ratio is determined by being divided into a base metal portion of each element and an extremely-high intensity ratio caused by a nonmetal inclusion in a discharge time set beforehand, and converted into a composition based on a calibration curve between the intensity ratio and the composition determined beforehand by a standard sample from the intensity ratio of the nonmetal inclusion portion. The operation is performed relative to each element, to thereby determine the nonmetal inclusion composition.
