Studying the structural-phase substance of solid and powder brass samples by X-ray diffractometry

Abstract

The use of powder as an alloying element in the formation of various parts is a modern trend in mechanical engineering. It is common to use the added powder of a completely different type of material, and the requirements for the powder are constantly increasing. At the same time, an important characteristic of any method is the quality of the obtained powder, such as the degree of contamination by foreign impurities and the range of particle sizes. The most acute problem of obtaining powder is to preserve the original (not changed in the process of obtaining) material properties, as well as the need to prevent contamination and oxidation of particles. The aim of the work is to study the structural-phase state of solid and powdered brass samples. To achieve this goal it is necessary to solve the following tasks: to investigate the structural and phase state of a brass sample in the form of a cylinder; investigate the structural and phase state of a brass powder obtained by a high-speed dispersion method.Results: Using the X-ray microanalysis method, it has been established that the elemental composition of the studied material corresponds to the composition of brass L63; by X-ray analysis, it was found that the samples of the brass cylinder are a mixture of a solid solution of zinc in copper (Cu-Zn) with a zinc content of about 34% of the CuZn phase with a CsCl-type cubic crystal lattice. Brass powder samples have the same phase composition, but with a different ratio of these phases.
