FACTORS OF EXPERIMENTAL RESEARCH CHEMICAL COMPOSITION OF ALLOYS
The article discusses the relevance of conducting research on the chemical composition of alloys. The preparatory stages for the analysis of the alloy structure are considered. Chemical reagents for etching nonmet-allic structures in the allov are described, which further determine the chemical composition of the allov. Preliminary studies of the detail, such as studying the fracture of the sample, measuring its hardness, are considered. The algorithm and factors of studies of the chemical composition of the alloy of an arbitrary part are described. A comparative analysis of the hardness of the alloy of the part with other copper-based alloys is given. The application of the copper-zinc alloy state diagram to determine the chemical composition of the alloy is considered. The selection of the brand of brass is carried out in accordance with the factors considered in the work.
