Zhu, Jia-Ning (author), Zhu, Weijia (author), Borisov, Evgenii (author), Yao, Xiyu (author), Riemslag, A.C. (author), Goulas, Constantinos (author), Popovich, Anatoly (author), Yan, Z. (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

Fu, J. (author), Brouwer, J.C. (author), Hendrikx, R.W.A. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)The present work deals with oxide dispersion strengthened (ODS) Eurofer steel fabricated by powder metallurgy involving mechanical alloying and spark plasma sintering. A heat treatment route including normalising and tempering was applied to the as-produced steel, based on differential scanning calorimetry (DSC) measurement. The...journal article 2020

(author)This work studies the influence of the microstructure on the corrosion mechanism and susceptibility of as-brazed aluminum sheet. Various microstructures are obtained using postbrazing heat treatments developed to enhance the corrosion resistance of an AA4xxx/AA3xxx brazing sheet. The heat treatment results in a decrease of the matrix Si...journal article 2017

't Hart, W.G.J. (author), Kolkman, H.J. (author), Schra, L. (author)The Jominy end-quench test was applied to rods of the alximinium alloys T010 and X TO9I to obtain a decreasing cooling rate over the length of the rods. After heat treating to a high strength T6 and an overaged TT condition the corrosion properties and the microstructure were determined related to the cooling rate. No influence of cooling rate...report 1982
