摘要

采用高沉积率激光熔覆沉积技术制备了GH4169合金试样, 研究了沉积率为2.2 kg/h时GH4169合金的微观组织和拉伸断裂机制。结果表明:高沉积率激光熔覆沉积GH4169合金沉积态试样的析出相主要包括Laves相、针状δ相及不均匀分布的γ″和γ′强化相。拉伸测试结果表明, 沉积态GH4169高温合金的塑性和强度均低于锻件标准。

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.
