Закономерности формирования полиметаллических изделий методом аддитивной электронно-лучевой технологии

Abstract

Samples of functional-gradient materials of the "copper-aluminum" system on a stainless steel substrate were obtained by the method of additive electron-beam technology with wire filament. The heterogeneity of the materials structure in different areas of the structural gradient was studied by the method of optical microscopy. Functionally-gradient materials of various compositions with the presence of a smooth and sharp gradient of the structure from copper to copper-aluminum alloy have been investigated. The results indicate the presence of heterogeneities in the composition and structural defects in materials and the need to find ways to eliminate them.
