Abstract

By optical and scanning electron microscopy methods together with EBSD-analysis nickel-base superalloy ZhS6K-VI made by a selective laser melting sample structure was investigated. EBSD-analysis application allowed finding structure features, which do not observe during microscopic research: fragments primary orientation existence, which is inherited by melt baths; cracks development on boundaries between fragments with various crystallographic orientations.
