Abstract

Titanium alloy TA15, a pseudo α-alloy from the Ti–Al-Zr-Mo-V system, has garnered significant interest due to its high specific strength, excellent corrosion resistance, and superior heat resistance. This study investigates the high cyclic fatigue behavior of 3D-printed TA15, highlighting its application in aerospace, automotive, and biomedical industries. Traditional manufacturing of elements and components from TA15 involves billets and forging, ensuring high-quality metal but incurring high costs due to extensive and complex machining processes. Additive manufacturing, particularly by electron beam melting (EBM) technology, offers a promising alternative by reducing material waste and enabling rapid prototyping. This research evaluates the mechanical properties, microstructure, and fatigue performance of TA15 specimens produced via EBM. Initial findings indicate that 3D-printed TA15 exhibits strength and comparable fatigue resistance to conventionally manufactured counterparts, making it a viable option for critical applications. The study provides insights into optimizing the AM process for TA15 to enhance its performance and reliability.

3d打印钛合金TA15的高周疲劳行为

钛合金TA15是一种来自Ti-Al-Zr-Mo-V体系的伪α-合金，由于其高比强度、优异的耐腐蚀性和优异的耐热性而引起了人们的极大兴趣。本研究研究了3d打印TA15的高周疲劳行为，重点介绍了其在航空航天、汽车和生物医学行业的应用。TA15元素和部件的传统制造涉及钢坯和锻造，确保了高质量的金属，但由于广泛而复杂的加工过程，导致成本高昂。增材制造，特别是电子束熔化（EBM）技术，通过减少材料浪费和实现快速成型，提供了一个有前途的替代方案。本研究评估了经EBM制备的TA15试样的力学性能、显微组织和疲劳性能。初步研究结果表明，3d打印的TA15具有与传统制造的同类材料相当的强度和抗疲劳性，使其成为关键应用的可行选择。该研究为优化TA15增材制造工艺以提高其性能和可靠性提供了见解。
