Deformations of Ti-6Al-4V additive-manufacturing-induced isotropic and anisotropic columnar structures: Insitu measurements and underlying mechanisms.
Jo-Chi Tseng,Wei-Chin Huang,Wei Chang,Arno Jeromin,Thomas F. Keller,Jun Shen,Andrew Chihpin Chuang,Chun-Chieh Wang,Bi-Hsuan Lin,Lia Amalia,Nien-Ti Tsou,Shao-Ju Shih,E-Wen Huang,E-Wen Huang +13 more
TL;DR: It is found that the texture development of the columnar structures and the distribution of crystallite orientation achieved by different processing conditions during additive manufacturing have important effects on the mechanical properties.

Multiple α sub-variants and anisotropic mechanical properties of an additively-manufactured Ti-6Al-4V alloy
Yinling Zhang,Yinling Zhang,Chen Zhuo,S.J. Qu,A.H. Feng,Guangbao Mi,Jun Shen,Jun Shen,Xu Huang,Daolun Chen +9 more
TL;DR: In this paper, the anisotropy in the mechanical properties of additively-manufactured materials is still poorly understood and the authors aimed at elucidating crystallographic feature-anisotropic-mechanical property relationship for a Ti-6Al-4V alloy manufactured via selective electron beam melting.
