摘要：

Regularities of structure formation of bimetallic elements of aluminum-manganese bronze CuAl9Mn2 and low-alloy structural steel A516 using different sequences of component deposition during printing by wire-arc additive manufacturing are investigated. It is found out that the sequence of material deposition affects the product structure and mechanical properties. Due to the differing melting points of bronze and steel, the samples show either a sharp fusion boundary between the components or their highly diluted mixture. According to the mechanical tests, the ultimate strength of the steel/bronze specimens reaches 450 MPa, while that of the bronze/steel specimens has lower values (220-350 MPa) due to the presence of defects.
