The effects of induction heating local heat treatment and vacuum furnace overall heat treatment on the residual stress and tensile properties of laser deposition repair GH4169 superalloy are investigated. As compared with as-deposited samples, direct aged microstructure of laser deposition repair GH4169 superalloy changes little, and still presents the microstructural characteristic of columnar dendrites which grow epitaxially from the substrate. But Laves phase of interdendritic dissolves partly. The residual stress is reduced. The tensile strength is significantly improved. After local heat treatment, the residual stress decreases averagely more than 33%, and the tensile strength reaches over 86% of the mechanical properties of forgings. After vacuum heat treatment, the residual stress decreases averagely more than 43%, and the tensile strength reaches the mechanical properties of forgings.
