| 1 | Study on the hot deformation behavior of Al-Zn-Mg-Cu-Cr aluminum alloy during multi-stage hot compression显示文摘The mechanical behavior and microstructures of an Al-Zn-Mg-Cu-Cr aluminum alloy during multi-stage hot deformation were investigated by thermal stimulation test,optical microscopy,and transmission electron microscopy.The true stress vs true strain curves and the microstructure evolution of two hot deformation procedures were gained.The flow stress of the alloy studied decreases with increasing the deforming passes and declining the temperature,and the larger the temperature decline between adjacent stages,the larger the peak stress fall is.The stress-strain behavior mainly result from the dynamic recovery during deformation,the static recovery and re-crystallization in the delay time,and the second phases precipitated from the matrix at high temperature. | Gaoyong LIN Xiaoyan ZHENG Wei YANG Di FENG Dashu PENG | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，2： | 8 |

| 4 | In-situ A1/24Si Functional Graded Materials Prepared by Electromagnetic Separation显示文摘Cylinder-like in-situ Al/24Si FGMs were produced by using electromagnetic separating process. Si primary phasereinforced layer with volume fraction as high as 16 pct was formed at the outer region of the cylinder-like sampleswhere the local hardness and wear resistance were enhanced remarkably. Moreover, both of strength and ductility inthe inner region provided insurance of reliable strength for this as-cast gradient material. It indicated that generalmechanical properties such as good wear resistance at the outer region and good ductility in the central part couldbe obtained with the optimized redistribution of the Si primary particles under the electromagnetic force. | KeLI JunWANG DaSHU BaodeSUN YaoheZHOU | 2002 | Journal of Materials Science & Technology2002，18，5： | 2 |
| 5 | AXIAL LOADS ACTING ON MANDREL IN COPPER RIFLED TUBE DRAWING PROCESS显示文摘Stresses and axial loads acting on the mandrel in the copper rifled tube drawing process were analysed,and factors affecting on the axial loads on mandrel were discussed.Results show that the depth of the mandrel dragged into sizing zone and lubrication have major influence on drawing loads and fin shapes. | Peng Dashu Yang Bin Wang Feiyong Yang Linbin | 1996 | Transactions of Nonferrous Metals Society of China1996，6，1： | 1 |

| 7 | NUMERICAL MODELLING OF GOLD-ROLLBONDING OF CLAD METAL SHEETS显示文摘An analytical model based on the rigid-plastic finite-element formulation for slightly compressible materials is newly proposed to examine the bonding behavior at the roll gap during clad metal sheets rolling. The interfacial elements inserted between the two metals, which are characteristic of the shear-susceptible deformation with the help of the shear factor in the expression of effective strain rate,are used to model the relative slidding at the interface. It is found that the proposed method is applicable to the simulation of clad metal sheets rolling. | Luo Chunhui Peng Dashu Xu Zuohui (Department of Materials Science and Engineering, Central South University of Technology, Changsha 410083, China) | 1997 | Journal of Central South University1997，9，2： | 0 |
| 8 | Effects of Co doping on electronic structure and electric/magnetic properties of La_(0.1)Bi_(0.9)FeO_3 ceramics显示文摘In this work,we report the influence of Co-doping on the electronic band structure,dielectric and magnetic properties of La0.1Bi0.9Fe1-xCoxO3 ceramics.X-ray photoelectron spectroscopy investigation shows that Co dopant can shift the valence band spectrum and core-level lines of constituent elements towards higher bind energy regions simultaneously increase the concentration of oxygen vacancies in ceramics.The effects of dopant are discussed with focus given to the Co-doping induced enhancement of electrical conductivity and resistive switching phenomena. | WANG ShouYu FENG Yu LIU WeiFang YU DaShu LI DeJun | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，10： | 0 |
