and bonding of metal face-sheet/ powders interface. Compared with mold-compacting, powder densification process and deformation characteristic of interface were studied for the first time in the process... produced in powders, thus powders became lamellar structure under rolling pressure. Powders were compacted bonded and atomic force formed among the powders. Metal aluminum sheet exposed fresh metal surface......

Preparation of Ti-Al alloy sheet by electron beam physical vapor deposition MA Li(马李), HE Xiao-dong(赫晓东), SUN Yue(孙跃) Center for Composite Material, Harbin Institute of Technology, Harbin 150001... sheet with dimension of 450 mm×450 mm×0.2 mm was prepared by electron beam physical vapor deposition(EB-PVD) technology. The surface and cross-section pattern of as-deposited sample were studied by SEM......
; Abstract: The failure of AA3003 aluminum alloy sheet metal was predicted for non-isothermal... of viscous medium ranges from 150 to 180 ℃, the formability of sheet metal can be improved to a full extent. The validity of the predictions is examined by comparing with experimental results. Key words......
Center, Shanghai 200030, China;2.Shanghai Volkswagen Automotive Company Ltd.(SVM) Abstract:In sheet metal forming, drawbeads are often used to control uneven material flow which may cause defects such as wrinkles, fracture, surface distortion and springback.Appropriate setting and adjusting the drawbead force is one of the most important parameters in sheet metal forming process control. This paper......
by hot uniaxial tensile test of sheet metal. Based on the assumption that granule medium is applied to extended Drucker-Prager linear material model, the finite element model of HGMF process is established and the effect of technological parameters, such as forming temperature, blank-holder gap and drawing ratio, on the sheet metal formability, is studied. The limit drawing ratio curve of AA7075......
