| 1 | Effect of Sc and Zr on the in-plane anisotropy of Al-Mg-Mn alloy sheets显示文摘The Al-Mg-Mn alloy sheets with and without trace Sc and Zr were investigated by means of tensile test, X-raydiffraction, optical microscope, and transmission electron microscope. The indexes of in-plane anisotropy (IIPA) of their ten-sile mechanical properties were calculated and their inverse pole figures were obtained by Harris method. The two alloysheets have the same law of in-plane anisotropy and remarkable in-plane anisotropy of mechanical properties, and the IIPA ofthe alloy sheet with Sc and Zr is bigger than that of the alloy sheet without Sc and Zr. The relationships of the in-plane ani-sotropy and the anisotropy of the crystallographic texture were analyzed based on the model of monocrystal. It is the com-mon action of the anisotropy of crystallography and microstructures that causes the in-plane anisotropy of their mechanicalproperties, but the major cause is the {110}<112> crystallographic texture. The trace Sc and Zr can promote the formationand stabilization of the {110}<112> texture, inhibit the formation of the {100}<001> texture, and increase the in-plane ani-sotropy of the alloy sheet containing trace Sc and Zr. | PENG Yongyi YIN Zhimin YANG Jin DU Yuxuan | 2005 | Rare Metals2005，24，3： | 6 |
| 2 | Mechanism,condition and characteristics for the formation of the network structure in Zr-Al-Ni-Cu bulk metallic glasses显示文摘Mechanism,condition and characteristics for the formation of the network structure in a group of Zr-Al-Ni-Cu bulk metallic glasses(BMGs) were investigated.The results show that the constituent segregation and/or the symplastic growth would be the mechanisms for the formation of the cell structure in the present Zr-Al-Ni-Cu BMGs.The cell structure can be easily obtained for the glass forming alloys whose compositions locate nearby the eutectic point.The shorter the distance is from the eutectic point,the larger the cell and the thicker the cell wall of the network structure will be.The present investigation would provide useful information for the development of the BMG with the network structure. | AN WeiKe DING DaWei CAI AnHui ZHOU GuoJun LUO Yun LI JiangHong PENG YongYi | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，6： | 2 |
| 3 | Effect of Scandium and Zirconium on Mechanical and Exfoliation Corrosion Properties of Al-Mg-Mn Alloys显示文摘To quest for the best combination of mechanical properties and exfoliation corrosion resisting property of Al-Mg-Mn base alloys, and to seek after the effect of Sc and Zr on mechanical and exfoliation corrosion properties of Al-Mg-Mn alloys, comparative research technique was used, the mechanical properties of Al-Mg-Mn alloys with and without minor Sc and Zr treated by different annealing were measured, the degrees of exfoliation corrosion for these alloys through accelerated exfoliation corrosion test were evaluated, and polarization curves of these alloys were measured, too. The micro-morphologies of corrosion specimens were observed by SEM and the corrosion product was analyzed using EDS. Optical microscope and TEM were used, the relationship between their microstructures and mechanical properties, exfoliation corrosion resisting property was investigated, and the results show that the addition of minor Sc and Zr can enhance the strength greatly and also improve the combination of strength and plasticity. Moreover, the addition of minor Sc, Zr does not cause appreciable decrease of exfoliation corrosion resisting property, the Al-Mg-Mn-Sc-Zr alloy annealed at 350 ℃ for 1 h has excellent combination of mechanical properties and exfoliation corrosion resisting property, the satisfied combination of mechanical properties nad exfoliation corrosion resisting property can be obtained by means of adding minor Sc and Zr, decreasing the content of Mn, and adopting reasonable annealing practice. | Peng Yongyi Yin Zhimin | 2006 | Journal of Rare Earths2006，24，2： | 1 |
| 4 | Hybrid C8-BTBT/In GaAs nanowire heterojunction for artificial photosynaptic transistors显示文摘The emergence of light-tunable synaptic transistors provides opportunities to break through the von Neumann bottleneck and enable neuromorphic computing.Herein,a multifunctional synaptic transistor is constructed by using 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene(C8-BTBT)and indium gallium arsenide(InGaAs)nanowires(NWs)hybrid heterojunction thin film as the active layer.Under illumination,the Type-I C8-BTBT/InGaAs NWs heterojunction would make the dissociated photogenerated excitons more difficult to recombine.The persistent photoconductivity caused by charge trapping can then be used to mimic photosynaptic behaviors,including excitatory postsynaptic current,long/short-term memory and Pavlovian learning.Furthermore,a high classification accuracy of 89.72%can be achieved through the single-layer-perceptron hardware-based neural network built from C8-BTBT/InGaAs NWs synaptic transistors.Thus,this work could provide new insights into the fabrication of high-performance optoelectronic synaptic devices. | Yiling Nie Pengshan Xie Xu Chen Chenxing Jin Wanrong Liu Xiaofang Shi Yunchao Xu Yongyi Peng Johnny C.Ho Jia Sun Junliang Yang | 2022 | Journal of Semiconductors2022，43，11： | 1 |
