(author)Understanding and controlling the composition segregation during powder spreading is of key importance in the additive manufacturing (AM) of composite materials. Under this circumstance, the segregation behavior of WC/316 L composite powders during spreading in laser powder bed fusion (LPBF) AM was numerically investigated by the discrete...journal article 2022

Zhang, Z. (author), Zhang, S. (author), Yao, Z. (author), Tao, X. (author), Cao, X. (author), Zhang, P. (author), Kuang, P. (author), Fu, Y. (author), van Dijk, N.H. (author), van der Zwaag, S. (author)The effect of thermal aging of homogenized Fe-Au and Fe-Au-W alloys, irradiated at room temperature with hydrogen ions, was studied for an aging treatment at 300 °C for aging times up to 100 h. The aging behavior of the Fe-based alloys is compared to the results for pure Fe. The precipitation behavior of Au-rich and W-rich precipitates and...journal article 2021

Fu, Qiang (author), Yi, Sinan (author), Chen, B. Y. (author), Bui, Tinh Quoc (author), Hu, Xiaofei (author), Yao, Weian (author)Numerical study on crack propagation are of great importance for structure design and assessment. In this contribution, the floating node method (FNM) is combined with the symplectic analytical singular element (SASE) to form a new crack-tip element. The four node quadrilateral crack-tip element contains a SASE for the crack tip area to...journal article 2020
