Abstract
In this study, a lightweight Al 24 . 2 Si 3 . 25 Cu 24 . 2 Ni 24 . 2 Ti 24 . 2 high-entropy alloy was developed by sonication blending of the pure elements followed by the high-temperature sintering in the nitrogen gas environment. Microstructural characterization of the sintered alloy showed a fair dispersion of the elemental particles in the matrix during the blending process and the absorption of nitrogen, which led to the formation of multiple intermetallic compounds, including the nitrides, during the sintering process. Mechanical characterization of the sintered alloy revealed significantly high microhardness values with relatively lower compressive strength in Al 24 . 2 Si 3 . 25 Cu 24 . 2 Ni 24 . 2 Ti 24 . 2 alloy.
在这项研究中，一个轻量级的al24。2 Si 3。25 Cu 24。2 . Ni 24。2 Ti 24。采用纯元素超声共混，再在氮气环境下高温烧结的方法制备了高熵合金。烧结合金的显微组织表征表明，在共混过程中，元素颗粒在基体中均匀分散，氮的吸收导致烧结过程中形成包括氮化物在内的多种金属间化合物。烧结合金的力学性能表明，al24的显微硬度值较高，而抗压强度相对较低。2 Si 3。25 Cu 24。2 . Ni 24。2 Ti 24。2合金。
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.
