| description | The excellent comprehensive high-temperature performance of Ti2AlNb alloy makes it a potential substitute for some nickel-based alloys， serving as a key structural material for weight reduction in aviation engines. In response to the lightweight design requirements of future high-performance aviation engines， a combination of statistical comparison， control experiments， finite element simulation analysis， and other methods are used to analyse the material properties， alloy cold/hot processing performance， weight reduction benefits， etc. The advantages， potential， and remaining issues of the alloy’s application in aviation engines are discussed. The analysis results indicate the feasibility of using Ti2AlNb alloy in aviation engines， with significant advantages in weight reduction： the alloy achieves a good balance of strength， toughness， and plasticity without obvious shortcomings； it has acceptable cold and hot processing performance， and can obtain engineering-sized parts through deformation， casting， and other methods； its combustion resistance is superior to traditional titanium alloys； when applied to static components such as casings， it can achieve a weight reduction of 35.3% compared to high-temperature alloys， and when applied to integral blade/disks and rotor components， it can achieve a weight reduction of 37.3% compared to nickel-based high-temperature alloys. |
