    Abstract

    The GH4169 alloy samples are fabricated by the high-deposition-rate laser metal deposition (HDR-LMD) technique and their microstructures and tensile properties are investigated when the deposition rate is 2.2 kg/h. The precipitated phases of the HDR-LMDed samples mainly include Laves phase, acicular δ phase and non-uniformly distributed γ″ and γ′ phases. The tensile test results show that the plasticity and strength of the as-deposited superalloy are both lower than the forging standard.
