Liang, X. (author), Bos, Cornelis (author), Hermans, M.J.M. (author), Richardson, I.M. (author)A cellular automata (CA) model has been developed for solidification simulation considering the kinetic undercooling at the interface. The state-of-the-art model incorporates a decentered growth algorithm to suppress the grid anisotropy and a generalized height function method to calculate the curvature accurately. To develop a CA model which...journal article 2023

(author), Popovich, V. (author)Laser powder bed fusion (L-PBF), categorized as additive manufacturing technique, has a capability to fabricate NiTi (Nitinol) shape memory alloys with tailorable functional properties and complex geometries. An important processing parameter, hatch distance (h), is often related to macroscale structural defects; however, its role on...journal article 2022

Zhu, Jia-Ning (author), Borisov, Evgenii (author), Liang, X. (author), Farber, Eduard (author), Hermans, M.J.M. (author), Popovich, V. (author)Nitinol (NiTi) shape memory alloys fabricated by Laser Powder Bed Fusion (L-PBF) Additive Manufacturing (AM) have attracted much attention in recent years, as compared with conventional manufacturing processes it allows to produce Nitinol parts with high design complexity. Avoidance of defects during L-PBF is crucial for the production of...journal article 2021
