Investigating the plastic anisotropy and hardening behavior of a commercial Zn–...
Cauvin, Ludovic; Raghavan, Balaji; Jin, Jianqiang; Bouvier, Salima; Wang, Xiaodong; Meraghni, Fodil; Alves, J. L.The aim of this work is to conduct a comprehensive examination of the anisotropic plastic behavior of a sheet of commercial Zn-Cu-Ti alloy, undergoing different quasi-static deformation paths at room temperature. Various mechanical tests are performed, including uniaxial and bi-axial tensile tests, Meuwissen and shear tests, obtaining homogeneous and heterogeneous strain fields. It was observed that under monot...
Reactive infiltration processing of SiC/Fe-Si composites using preforms made of...
Zhu, Dan; Gao, Mingxia; Pan, Hongge; Liu, Yongfeng; Wang, Xiaodong; Pan, Yi; Oliveira, Filipe J.; Vieira, Joaquim M.A reactive infiltration processing of SiC/Fe-Si composites using preforms made of coked rice husks (RHs) and SiC powder in different ratios is reported, in which FeSi2 alloy was used as infiltrant. The preforms were heat-treated at 1550 degrees C for 6 h prior to the infiltration. The coked RHs, which are composed of SiO2 and C, were converted to SiC and poorly crystallized C by carbothermal reduction during th...
Management of Water Pollutants Based on Multi-Criteria Analysis and Fuzzy Logics
Cescotto, Serge; Roubens, Marc; Rigo, Nicolas; Gao, Shixiang; Wang, Xiaodong; Zhang, Aiquan; Lourenço, Nelson; Zhou, Jiti; Xiang, XueminThis work has been developed in the frame of the MANPORIVERS research project funded by the European Commission. The goal is to identify effective and sustainable policies for the management of surface and ground water pollutants, taking account of their relationships with food production and human health. A methodology based on the combination of fuzzy logics and multicriteria analysis is proposed as a decisio...
