Anisotropic response of Ti-6Al-4V alloy fabricated by 3D printing selective laser melting (2017, background): “The products manufactured by SLM tend to have a unique structure of column grain [5].”
A comparative study of additive manufacturing techniques: Residual stress and microstructural analysis of CLAD and WAAM printed Ti–6Al–4V components (2016, background): “In the early stage of solidification gas condensation of dissolved gas in the melt (generally hydrogen coming from moisture or contamination of the feedstock material [28]) can also form pores upon freezing as a result of the difference of solubility of such gas in the liquid and solid phase [29].”
Current Status and Perspectives on Wire and Arc Additive Manufacturing (WAAM) (2019, background): “Columnar β-grains from prior layers with grain boundary-α [47] are also prominent undesired features, causing premature failure in transverse loading solicitations [46,48].”
Numerical analysis of heat transfer and fluid flow in multilayer deposition of PAW-based wire and arc additive manufacturing (2018, background): “During the solidification of Ti-6Al-4V in WAAM process, the high temperature β-grains (bcc) grow epitaxially, columnar can extend through the entire wall, which results in characteristic anisotropic mechanical properties [6].”
Wire-feed additive manufacturing of metal components: technologies, developments and future interests (2015, neutral): “Wire and arc additivemanufacturing (WAAM) is another popular wire-feed AM technology.”
Control of residual stress and distortion in aluminium wire + arc additive manufacture with rolling (2018, background): “This is primarily due to large columnar dendritic grains that grow epitaxially during deposition [35].”
Towards understanding grain nucleation under Additive Manufacturing solidification conditions (2020, background): “Wang et al [43] obtained a mix of columnar and equiaxed grains during the WAAM process for Ti6Al4V alloy.”
