Abstract

The fabrication of ternary Cu–Mn–Al alloys through self-propagating high-temperature synthesis and their thermoelectric properties, such as electrical resistivity and the Seebeck coefficient in a wide range of temperatures, were studied. XRD analysis identified the Heusler compound Cu₂MnAl in the synthesized compositions as a main precipitated phase. In addition, different secondary phases (Al₂Cu, Cu₃Al AlCu, and Mn) appear depending on an excess of aluminum or manganese in the green mixture. The magnetization (M–H) curves constructed for the studied alloys showed their weakly ferromagnetic behavior.

铜锰铝合金的自蔓延高温合成：热电和磁性能

摘要研究了通过自蔓延高温合成法制造的三元铜锰铝合金及其在宽温度范围内的热电特性，如电阻率和塞贝克系数。XRD 分析确定了合成成分中作为主要沉淀相的 Heusler 化合物 Cu2MnAl。此外，不同的次生相（Al2Cu、Cu3Al AlCu 和 Mn）的出现取决于绿色混合物中铝或锰的过量。所研究合金的磁化（M-H）曲线显示其具有弱铁磁性。

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
