摘要

陶瓷颗粒增强铝合金具有高刚度、高强度、高疲劳性能等优点，是国内外航空领域应用潜力较大的结构材料。本文以质量分数5% 的TiB

颗粒增强2024铝合金材料为研究对象，开展了材料疲劳性能试验研究，对比了不同材料批次、材料方向、板厚与应力集中系数等变量对材料疲劳性能的影响规律。结果显示，应力集中系数为1.0时，材料批次、材料取向和板材厚度对其疲劳性能的影响较小，疲劳性能一致性较好，相比基体材料（2024–T3），疲劳性能提升30%以上；应力集中系数K

为3.1时，板厚变化对条件疲劳极限影响显著。本文为陶瓷颗粒增强铝合金在航空应用领域提供研究基础。

Abstract

Ceramic particles reinforced aluminum alloy is a highly promising structural material with great potential for aeronautical applications due to the advantages of high stiffness

high strength and excellent fatigue property. This paper takes TiB

particle reinforced 2024 aluminum alloy material with a mass fraction of 5% as the research object

conducts material fatigue performance test research

and compares the influence of variables such as different material batches

material directions

plate thicknesses

and stress concentration factors on material fatigue performance. The results show that the influence of material batches

material directions and thickness on the fatigue performance is relatively small when the stress concentration factor is 1.0. The inclusion of TiB

particles increases the fatigue limit by 30%. When K

= 3.1

thickness shows some effects on the fatigue limit. The results provide a research foundation for the application of TiB

reinforced aluminum alloy in aeronautical applications.
