TL;DR: In this article, different heat treatments were performed based on three approaches in order to study the effects of heat treatments on the unique microstructure formed during the EBM fabrication process.
Journal ArticleDOI
Effects of the microstructure and porosity on properties of Ti-6Al-4V ELI alloy fabricated by electron beam melting (EBM)
TL;DR: In this paper, the relationship between the porosity and the mechanical properties of the Ti-6Al-4V ELI (extra low interstitials) alloy has been investigated.
Journal ArticleDOI
Microstructure, static properties, and fatigue crack growth mechanisms in Ti-6Al-4V fabricated by additive manufacturing: LENS and EBM
TL;DR: In this article, the effects of post-AM heat treatments on microstructure and properties were also studied and the results are systematically presented and discussed from the material/process optimization, structural design, and fatigue life prediction perspectives.
Journal ArticleDOI
Microstructure Evolution, Tensile Properties, and Fatigue Damage Mechanisms in Ti-6Al-4V Alloys Fabricated by Two Additive Manufacturing Techniques
TL;DR: In this paper, structural materials fabricated by two additive manufacturing (AM) techniques were investigated: Laser Engineered Net Shaping (LENS) and Electron Beam Melting (EBM), and the results were systematically presented and discussed from both the material/process optimization, as well as structural design and fatigue life prediction perspectives.
Journal ArticleDOI
Fatigue crack growth mechanisms at the microstructure scale in as-fabricated and heat treated Ti-6Al-4V ELI manufactured by electron beam melting (EBM)
TL;DR: In this paper, the effect of the as-fabricated EBM microstructure and fatigue crack growth was investigated and compared to that of the equiaxed β annealed micro-structure obtained by annealing above the β transus temperature.
