(author), Tichelaar, F.D. (author), Mainali, D.P. (author), Hermans, M.J.M. (author), Popovich, V. (author)Additive manufacturing of NiTi shape memory alloys has attracted attention in recent years, due to design flexibility and feasibility to achieve four-dimensional (4D) function response. To obtain customized 4D functional responses in NiTi structures, tailorable phase transformation temperatures and stress windows as well as one-way or two-way...journal article 2023

Jiang, Quanxin (author), Morete Barbosa Bertolo, V. (author), Popovich, V. (author), Sietsma, J. (author), Walters, C.L. (author)Macroscale cleavage fracture toughness of high strength steels is strongly related to the fracture of hard microstructural inclusions. Therefore, an accurate determination of the local stress on these inclusions based on the matrix stress is necessary for the statistical modelling of macroscale cleavage fracture. This paper presents...journal article 2021

(author), Zhu, Jia-Ning (author), Popovich, Anatoly (author)In this paper, laser powder-bed fusion (L-PBF) additive manufacturing (AM) with a high-temperature inductive platform preheating was used to fabricate intermetallic TiAl-alloy samples. The gas atomized (GA) and mechanically alloyed plasma spheroidized (MAPS) powders of the Ti-48Al-2Cr-2Nb (at. %) alloy were used as the feedstock material. The...journal article 2020
