Abstract

Recently, the additive manufacturing for metal has become popular. It is possible to manufacture the complex shape by the additive manufacturing. However, the dimensional accuracy and surface roughness of product by additive manufacturing is inferior. The machining as post process is necessary. We aimed metal forming for one of post processes. High dimensional accuracy and smooth surface roughness are achieved by metal forming. In addition, it is expected the mechanical properties of product is improved by metal forming. In this study, the mechanical properties of a plate of aluminum alloy, which was rolled after additive manufacturing, was investigated. As the result, the microstructure of the plate was extremely fine. The fine microstructure was maintained after rolling. In addition, it was cleared that the plate had high strength and high ductility.
