This document specifies the method for the determination of the content of aluminum, calcium, copper, iron, mg, manganese, silicon and titanium in molybdenum-rhenium alloys. It is applicable to the determination of these elements in molybdenum-rhenium alloys. The determination range of each element is detailed in Table 1. The normative reference documents include GB/T 6682 and GB/T 8170. The principle of the method involves the analysis and measurement of the sample, using the Inductance Coupled Plasma Atomic EmissionSpectrometer. Terms and terms are not defined in this document. The sample is analyzed by hydrogen oxidation to measure the emission intensity of each element under nitric acid medium. Its mass concentration and mass fraction are derived from the working Linear dispersion.
