摘要

我们研究了采用不同电子束熔炼模式生产的因科镍尔 718 难熔合金。我们分析了合金在初始状态和硬化热处理后的相组成和微观结构的具体特征。对合金样品进行单轴拉伸试验后的断裂面进行了分析。结果表明，材料的断裂是根据韧性机制发生的。然而，断裂表面含有大量未熔区域和气孔形式的缺陷，这是使用添加剂技术从粉末材料中获得的产品的典型特征。研究表明，分析合金的断裂是由结构中存在的未熔区和δ相金属间颗粒引起的。

Specific Features of the Structure and Fracture of the Inconel 718 Alloy Prepared by the Method of Electron-Beam Melting

We study Inconel 718 refractory alloy produced by using different modes of electron beam melting. The phase composition and specific features of the microstructure of alloy are analyzed both in the initial state and after hardening heat treatment. The fracture surfaces of the samples of alloy are analyzed after uniaxial tensile tests. It is shown that the fracture of the material occurs according to the ductile mechanism. However, fracture surfaces contain significant amounts of defects in the form of unmolten areas and porosity, which is typical of the products obtained by using additive technologies from powder materials. It is shown that the fracture of the analyzed alloy is provoked by the presence of unmolten areas and intermetallic particles of the δ-phase in the structure.
