| Abstract Scope |
Alloys composed of refractory metals (such as niobium, tantalum, and titanium) and light metals (such as aluminum, magnesium) exhibit properties including high melting points, oxidation resistance, and high strength, making them critical materials in fields such as aviation, aerospace, superconductivity, and additive manufacturing. However, due to the significant differences in properties of density, melting point, and vapor pressure between refractory and light metals, conventional preparation techniques of melting and powder metallurgy—which tend to involve high temperatures and pressures—frequently result in alloy compositions that deviate from the designed targets, adversely affecting subsequent applications. To address this issue, this study proposes a method for controlling the composition of tantalum-aluminum by utilizing exothermic local chemical reactions to enhance interdiffusion of alloy components, offering a new perspective on the preparation of refractory metal alloy powders. |
