for applications in both aerospace and automotive industries[1, 2]. Especially, the TiAl-based alloys sheet can be used as thermal protection system panel, exhaust nozzle, low-pressure turbine blades... impurities in the prepared sheet that usually has poor density. As a new technology of sheet preparation, electron beam-physical vapor deposition (EB-PVD) can be used to prepare the brittle materials sheet......
in Fig. 11. It can be seen that the region corresponding to the undersurface of the actuator projecting on the sheet has larger current density. Fig. 11 Distribution of current density... to the undersurface of the actuator projecting on the sheet. Therefore, the coil conductor can be designed according to the wanted shape of the sheet. 2) The distribution of magnetic forces on the uniform pressure......
steel. This can result in restrictions in part geometry, then limiting automotive design[1]. Therefore, the new technology that can improve the formability of aluminum alloy sheet is required. Viscous pressure forming(VPF) is a new sheet flexible forming technology. The previous investigations show that VPF can improve the sheet formability[2-7]. VPF uses a semi-solid, flowable, highly viscous......
Experimental and finite element analysis for fracture of coating layer of galvannealed steel sheet S. I. KIM1, J. U. HER2, Y. C. JANG2, Y. LEE2 1. Sheet Products and Process Research Group, POSCO...: Mechanical properties of galvannealed (GA) steel sheet used for automotive exposed panel and predicted failure phenomenon of its coating layer were evaluated using finite element method. V-bending test......
Influence of melt-treatment on material constants of aluminum sheet used for easy-open can during hot deformation CHEN Yong-lu(陈永禄), FU Gao-sheng(傅高升), CHEN Wen-zhe(陈文哲) College of Materials... effect of all kinds of metallurgy defects. The Q and n values of the sheet prepared by high-efficient melt-treatment are the least, while the m value is the biggest, and the sheet can deform easily......
, the total power needed for a bimetal sheet extrusion process can be obtained by summing the internal power and the power dissipated on all frictional and velocity discontinuity surfaces.... Fig. 6 Cross-section of bimetal sheet before extrusion (Unit: mm) Table 1 Extrusion conditions used in analysis The developed upper bound solution can be used for the analysis of bimetal sheet......
