摘要

随着航空发动机涡轮叶片需求的不断增长,高温合金粉末在制造过程中的资源消耗和环境影响日益显著。以IN718镍基高温合金粉末为研究对象,建立了一种基于粉末混合的回收方法。通过将经过筛分的再生粉末与新粉末以1:1的质量比混合,进行综合表征测试,包括粉末形貌分析、粒度分布、叶片可打印性评估、机械性能测试(25°C和650°C的抗拉强度)和显微硬度测试,表明混合后的粉末保持了与新粉末相当的性能特征,没有统计学上的显著差异。此外,本研究还将生命周期评价(LCA)方法引入到高温合金粉末回收领域,为航空航天制造业的可持续发展提供了新的技术途径。通过对混合粉回收过程中环境影响的定量分析表明,该方法可减少45%的碳排放和48%的能耗。

Sustainable Additive Manufacturing of IN718 Blades: Powder Recycling Strategies for Reduced Carbon Footprint.

With the growing demand for aero-engine turbine blades, the resource consumption and environmental impact of superalloy powder in the manufacturing process have become increasingly significant. This study focuses on IN718 nickel-based superalloy powder and establishes a recycling method based on powder mixing. By mixing sieved recycled powder with new powder at a 1:1 mass ratio, comprehensive characterization tests, including powder morphology analysis, particle size distribution, blade printability evaluation, mechanical property tests (tensile strength at both 25 °C and 650 °C), and microhardness measurements, demonstrated that the blended powder maintained performance characteristics comparable to new powder, with no statistically significant differences observed. Furthermore, this study introduces the life cycle assessment (LCA) methodology into the field of superalloy powder recycling, providing a novel technical approach for sustainable development in aerospace manufacturing. A quantitative analysis of environmental impacts throughout the blended powder recycling process indicates that this method can reduce carbon emissions by 45% and energy consumption by 48%.

期刊介绍: Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
