Abstract

Due to its exceptional characteristics, including high-temperature resistance, corrosion resistance, and oxidation resistance, titanium alloy is extensively utilized in advanced fields such as aerospace and biomedical applications. Additive/Subtractive Hybrid Manufacturing (A/SHM) combines the advantages of Additive Manufacturing (AM) and Subtractive Manufacturing (SM), facilitating the one-step fabrication of complex component structures with high precision and quality. This approach offers innovative design concepts and methodologies for the processing and manufacturing of titanium alloy components. This review recapitulates the evolution laws of microstructure formation of titanium alloys in A/SHM, including phase composition and grain morphology, and expounds the correlation between microstructure and mechanical properties. It encompasses the influence of different processes such as scanning speed and laser power in A/SHM on the microstructure of titanium alloys and conducts process optimization. It further analyzes the deficiencies and challenges in the current cognition of A/SHM and presents personal insights into future research directions. This review also introduces the industrial applications of titanium alloy components fabricated by A/SHM and emphasizes its extensive development potential.

增材/减材混合制造中的钛合金微观结构：综述

由于其优异的耐高温、耐腐蚀、抗氧化等特性，钛合金被广泛应用于航空航天、生物医学等先进领域。增材/减法混合制造（A/SHM）结合了增材制造（AM）和减法制造（SM）的优点，实现了高精度、高质量的复杂构件结构的一步制造。这种方法为钛合金部件的加工制造提供了创新的设计理念和方法。综述了钛合金在A/SHM中微观组织形成的演变规律，包括相组成和晶粒形貌，并阐述了微观组织与力学性能的关系。研究了扫描速度和激光功率等不同工艺对钛合金显微组织的影响，并进行了工艺优化。进一步分析了当前对A/SHM认知的不足和挑战，并对未来的研究方向提出了个人见解。本文还介绍了A/SHM制备钛合金部件的工业应用，强调了其广阔的发展潜力。
