高沉积率激光熔覆沉积GH4169合金的微观组织与拉伸性能
|
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2.2kg/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。
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,acicularδphase and non-uniformly distributedγ″andγ′phases.The tensile test results show that the plasticity and strength of the as-deposited superalloy are both lower than the forging standard.
