摘要

详细研究了Ni-13Al—2Y (at.%)和ni - 11al—4y (at.%)三元高温合金的显微组织、显微硬度和抗氧化性能。合金的显微组织由γ -Ni枝晶和残余共晶组成。Ni - 17y2金属间化合物和γ -Ni是共晶相混合物的主要成分。Ni-11Al-4Y合金的显微硬度值高于Ni-13Al-2Y合金,这是由于合金中相对较硬的共晶数量较多。随着Y浓度从2到4 at的增加。%,质量增益、氧化层厚度、氧化速率显著提高。两种合金的氧化层均由三层组成:NiO为表层,al2o3为金属/氧化物界面的内层,Al/Y混合氧化物为内层。尽管所研究的合金表现出相当好的水垢粘附性,几乎没有重要的水垢剥落,但它们表现出更快的氧化动力学和更高的质量增益。

Structural properties and cyclic oxidation behavior of Ni-Al-Y superalloys
The microstructure, microhardness, and oxidation resistance of ternary model Ni-13Al--2Y (at.%) and Ni-11Al-4Y (at.%) superalloys were studied in detail. The microstructures of alloys consisted of primary γ -Ni dendrites and residual eutectic. The Ni 17 Y 2 intermetallic and γ -Ni were the major constituents of the eutectic phase mixture. The microhardness value of Ni-11Al-4Y alloy was higher than that of Ni-13Al-2Y alloy because of the higher amount of relatively harder eutectic. With increasing Y concentration from 2 to 4 at.%, the mass gain, oxide scale thickness, and oxidation rate remarkably increased. For both alloys, the oxide scale was comprised of three layers: NiO as a surface layer, Al 2 O 3 as an inner layer in the metal/oxide interface, and mixed Al/Y oxides as an internal layer. Although the studied alloys exhibited fairly good scale adherence in conjunction with almost no important scale spallation, they exhibited faster oxidation kinetics along with higher mass gains.

期刊介绍: Kovove Materialy - Metallic Materials is dedicated to publishing original theoretical and experimental papers concerned with structural, nanostructured, and functional metallic and selected non-metallic materials. Emphasis is placed on those aspects of the science of materials that address: the relationship between the microstructure of materials and their properties, including mechanical, electrical, magnetic and chemical properties; the relationship between the microstructure of materials and the thermodynamics, kinetics and mechanisms of processes; the synthesis and processing of materials, with emphasis on microstructural mechanisms and control; advances in the characterization of the microstructure and properties of materials with experiments and models which help in understanding the properties of materials.
