Abstract

The aviation industry is a key market that promote additive manufacturing (AM) technology since there are huge demands for precision manufacture of high-value complex structural parts and repair of local defects. Extensive research has been conducted on AM process, characterization, and fatigue evaluation of titanium alloy, but there are rare comprehensive reviews on fatigue evaluation methods used for AM aero-engine blades. Rigorous tests, evaluation, and certification are necessary before AM technology is applied in aero-engine blade repair, although it has shown great advantages in different engineering fields. This paper introduces the application of AM technology in the manufacturing and repair of aero-engine titanium alloy blades, summarizes the key factors affecting the fatigue performance of AM titanium alloys, thoroughly discusses the fatigue mechanism, research methods, and process optimizations of AM parts, and compares the differences among several prediction models in fatigue evaluation of AM titanium alloys.

航空钛合金叶片增材制造、增材修复及疲劳评价研究进展

航空工业对高价值复杂结构件的精密制造和局部缺陷修复有着巨大的需求，是推动增材制造(AM)技术发展的关键市场。对钛合金的增材制造工艺、表征和疲劳评价进行了广泛的研究，但对增材制造航空发动机叶片疲劳评价方法的全面研究尚不多见。尽管增材制造技术在不同的工程领域显示出巨大的优势，但在将其应用于航空发动机叶片维修之前，需要进行严格的测试、评估和认证。介绍了增材制造技术在航空发动机钛合金叶片制造和维修中的应用，总结了影响增材制造钛合金疲劳性能的关键因素，深入探讨了增材制造零部件的疲劳机理、研究方法和工艺优化，并比较了几种增材制造钛合金疲劳评价预测模型的差异。

期刊介绍： Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
