摘要

FGH96 镍基粉末高温合金可作为航空发动机高性能涡轮盘的理想材料。采用4 种不同扫描方式分别对FGH96 进行激光熔化沉积。主要研究了不同扫描方式对FGH96 沉积态的组织和性能的影响。结果表明，沉积层的微观形貌主要为外延生长的柱状晶，平行扫描方式均发现有微裂纹产生，而往复扫描方式并未出现开裂现象。成形零件的显微组织主要由固溶体基体相、Laves 相和碳化物组成。采用层间相同平行往复方式所得的成形件具有较大的表面硬度，平均值为 389.3HV0.2。成形件具有优良的力学性能，断裂方式均为塑性断裂，采用层间相同平行往复方式可得到1065.29MPa 的抗拉强度、28.17% 的延伸率。

Abstract

Nickle-based powder superalloy FGH96 is regarded as one of ideal choices for the high-property turbine disk in an aero engine. In this paper

the FGH96 was laser melting deposited in four different scanning modes respectively. The purpose of this research is mainly to find out the effects of different scanning modes on microstructure

mechanical properties during laser deposited process. The results are shown as followed. The microstructure morphology of deposited layers is mainly epitaxially grown columnar crystal. Cracks are found in parallel scanning modes while none in zig-zag scanning mode. The main phases in samples are solid solutions

Laves phase and carbides. Sample made by parallel zig-zag mode with the same direction between layers has larger microhardness and the average is 389.3HV0.2. Its tensile strength is 1065.29MPa and the elongation is 28.17%. It has excellent mechanical properties and the fracture features of ductile fracture.
