报告题目:Multiscale modeling of the electrical and elasto-plastic behavior of architectured and nanostructured Cu-Nb composite wires 报 告 人:谷瑭 博士 法国巴黎矿业学校(Mines Paris Tech) 报告时间:4月5号(星期三)下午 15点 报告地点:南一楼东边三层力学系会议室 邀 请 人:黄敏生 教授 Nanostructured and architectured copper niobium composite wires are excellent candidates for the generation of intense pulsed magnetic fields (>90T) as they combine both high strength and high electrical conductivity. Multiscaled Cu-Nb wires are fabricated by accumulative drawing and bundling (a severe plastic deformation technique), leading to a multiscale, architectured and nanostructured microstructure exhibiting a strong fiber crystallographic texture and elongated grain shapes along the wire axis. A comprehensive study of the effective electrical and elasto-plastic behavior of this composite material will be presented. |
