Структура бронз систем Cu-Al и Cu-Al-Si напечатанных методом электронно-лучевого аддитивного производства

Abstract

In this paper, we consider the features of the formation of structures in the bronze systems copper-aluminium, copper-aluminum-silicon, which are formed as a result of the multiwire technology of electron-beam additive manufacturing. Metallography was used to study typical structural elements. Research is focused on identifying grains of different phases in the longitudinal and cross sections of the samples. Based on the studies performed, differences in the structure and phase composition for the systems Cu-Al and Cu-Al-Si under consideration were established.
