Abstract

The invention discloses a method for analyzing and detecting alloying elements in a beryllium-aluminum alloy. The method comprises the following steps: weighing a beryllium-aluminum alloy sample to be detected and 20% sodium hydroxide solution in the mass ratio of (0.1 to 5): 100, and putting into a polytetrafluoroethylene plastic beaker; dissolving at a low temperature; oxidizing by adding 30% hydrogen peroxide in a small amount drop by drop, and decomposing excessive hydrogen peroxide by heating after oxidizing; cooling to obtain a mixed solution; weighing the mixed solution, 50% hydrochloric acid and 50% nitric acid in the volume ratio of (5 to 10): (30 to 50): (10 to 20); acidizing and heating until the solution is absolutely clear; cooling and diluting the solution to the required volume with water; shaking the solution up to obtain the beryllium-aluminum alloy sample solution to be detected; then, plotting standard working curves; and finally detecting the samples. The method for analyzing and detecting alloying elements in a beryllium-aluminum alloy in the invention solves the problems of the determination of silver with higher content in the beryllium-aluminum alloy material and the influence thereof on other elements to be detected in the material in the analysis and detection using plasma emission spectra.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and in particular relates to an analysis and detection method of alloy elements in beryllium aluminum alloys. Background technique [0002] Among the existing chemical analysis methods for beryllium-containing materials, there are only chemical analysis methods for elements in beryllium copper and beryllium-nickel materials with a low content of beryllium (<5%), and the analysis method for impurity elements in pure beryllium. There is currently no corresponding method for the analysis of alloy elements in beryllium aluminum alloy materials (containing beryllium ≈ 60%). For beryllium aluminum alloy materials, they are different from beryllium copper, beryllium nickel and pure beryllium materials, and cannot be analyzed in terms of analysis methods. generic. Silver, silicon, cobalt, germanium, vanadium, titanium and other six elements are used as alloy components of beryllium alu...
