增材制造可以节省时间和成本，特别是对于由昂贵的钛合金制成的航空航天部件。本文对增材制造的 Ti-6Al-4V 块体的形貌、微观结构、化学成分和硬度进行了研究和讨论。使用 Ti-6Al-4V 线和 Nd:YAG 激光器沉积块（7 个珠宽，7 层高）。使用两组不同的参数并研究了三种不同的后热处理条件（竣工、600 摄氏度/4 小时、1200 摄氏度/2 小时）。实验揭示了增材制造的 Ti-6Al-4V 材料的基本性能与工艺参数和热处理的相关性，并对这些性能进行了全面讨论。 (C) 2011 Elsevier B.V. 保留所有权利。
Additive layer manufacturing offers a potential for time and cost savings, especially for aerospace components made from costly titanium alloys. In this paper, the morphology, microstructure, chemical composition, and hardness of additive manufactured Ti-6Al-4V blocks are investigated and discussed. Blocks (7 beads wide, 7 layers high) were deposited using Ti-6Al-4V wire and a Nd:YAG laser. Two different sets of parameters are used and three different post heat treatment conditions (as-built, 600 degrees C/4 h, 1200 degrees C/2 h) are investigated. The experiments reveal elementary properties of additive manufactured Ti-6Al-4V material in correlation to process parameters and heat treatments, which are discussed comprehensively.
