Cai, Yuxin (author), Liu, Qing feng (author), Meng, Zhaozheng (author), Chen, Mengzhu (author), Li, Weihua (author), Šavija, B. (author)High-frequency vibration helps to improve the compactness of concrete, but also causes the settlement of coarse aggregates (CAs) and then affects the durability of hardened concrete. In this paper, a numerical study combining multi-phase CA settlement model and multi-component ionic transport model is performed to understand the influence of...journal article 2022

Li, Shengli (author), Liu, Y. (author), Zhang, H. (author), Cai, Hongming (author), Sun, Fenglian (author), Zhang, Kouchi (author)In this study, SAC305 and SAC305-0.3Ni solder balls were soldered onto Cu, high temperature treated Cu (H-Cu) and graphene coated Cu (G-Cu) substrates, respectively. The microstructure, the interfacial reaction, and the hardness of the solder joints were investigated. The interfacial intermetallic compound (IMC) is Cu<sub>6</sub>Sn<sub>5</sub...journal article 2018
