Heat treatment to eliminate anisotropy of microstructure and high-temperature tensile properties of GH4169 superalloy by selective laser melting

Heat treatment to eliminate anisotropy of microstructure and high-temperature tensile properties of GH4169 superalloy by selective laser melting

The selective laser melted （SLM） GH4169 superalloy has a significant directional columnar dendritic solidification microstructure， which can cause severe mechanical property anisotropy and increase service risk. The GH4169 superalloy prepared by laser selective melting （SLM） technology is taken as t...
