| 2 | Characterization of a Mg_(95.5)Zn_(1.5)Y_(3)alloy both containing W phase and LPSO phase with or without heat treatment显示文摘The influence of solid solution treatment on the microstructure and corrosion resistance of as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy is characterized.The microstructure of the as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy mainly consisted ofα-Mg,W(Mg_(3)Zn_(3)Y_(2))phase,and the long period stacking ordered(LPSO)(Mg_(12)ZnY)phase.After solid solution treatment,most of the W phase disappears gradually with increasing solution treatment time,with only a small amount of W phase distributed as particle.The LPSO phase slightly dissolved into substrate,and its morphology transitions from blocky shape to rod shape.Solid solution treatment of Mg_(95.5)Zn_(1.5)Y_(3) exhibits excellent corrosion resistance,because the Y and Zn atoms became enriched in the matrix and the changed morphologies of the LPSO and W phases were modified through heat treatment.The alloy created with solid solution treatment at 520 ℃ for 10 hours exhibits corrosion potential of−1.419 V,suggesting a significant improvement in corrosion performance. | Li Zhumin Wan Diqing Huang Yi Ye Shuting Hu Yinglin | 2017 | Journal of Magnesium and Alloys2017，5，2： | 8 |
| 3 | Precipitation and responding damping behavior of heat-treated AZ31 magnesium alloy显示文摘Microstructure observation and dynamic mechanical analysis were carried out to in- vestigate the precipitation and responding damping behaviors of AZ31 magnesium alloy. All the strain amplitude-dependent damping curves of the aged alloys are located between the curves of solutionized and as-cast alloys, although they have different critical strain amplitudes. The G-L theory is employed to explain the damp- ing mechanism involving the interaction between the dislocation and the precipitated phase. In addition, a damping peak is observed at temperatures close to 330 °C for AZ31 magnesium alloy, which is related to the β-Mg17Al12 phase dissolution. | Diqing WAN Jincheng WANG Gaifang WANG Lin LIN Zhigang FENG Gencang YANG | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，1： | 5 |
| 4 | Growth morphology and evolution of quasicrystal in as-solidified Y-rich Mg-Zn-Y ternary alloys显示文摘A petal-like icosahedral quasicrystal with five branches,which is considered to be the representative morphology of the icosahedral quasicrystal,has been observed in the Y-rich Mg-Zn-Y ternary alloys. Moreover,the polygon-like mor-phology,another pattern of the icosahedral quasicrystal,has also been found in the Y-rich Mg-Zn-Y ternary alloys. The latter morphology results from the evolution of the former one. The growth mechanism of the petal-like morphology of the ico-sahedral quasicrystal was also discussed. Alloying composition,i.e.,Y element content,is a major factor inducing the mor-phology evolution of the icosahedral quasicrystal. | WAN Diqing YANG Gencang CHEN Sulin ZHU Man ZHOU Yaohe | 2007 | Rare Metals2007，26，5： | 4 |
| 5 | Regional cerebral blood flow imaging assessment of brain function reconstruction in elderly hemiplegia patients by body weight support treadmill training显示文摘The mechanism underlying body weight support treadmill training in elderly hemiplegic stroke patients is largely unknown.This study aimed to elucidate the changes of cortical blood flow in seven elderly patients with post-stroke hemiplegia before and after body weight support treadmill training by semi-quantitative analysis of regional cerebral blood flow assessed by single photon emission computed tomography.Body weight support treadmill training for 6 months was effective in improving cerebral blood flow and promoting the walking speed and balance recovery in elderly patients with post-stroke hemiplegia. | Wenqing Wang Yongping Liu Diqing Wang Yanshuang Li Jinglai Hao Hongwei Zhang Sheng Bi Changshui Weng | 2011 | Neural Regeneration Research2011，6，17： | 3 |
| 6 | Microstructure modification by La_2O_3 and its effect on wear resistance properties of as-cast ZL107 alloy显示文摘Modification of ZL107 aluminum alloy has been successfully achieved by using La2O3.The different casting parameters,including casting temperature as well as holding time and modifier content,were carried out to investigate the modification effects.The results show that the best modifier content is 1.0 wt.%,and the casting temperature has little effect.In addition,the wear behavior of modified and unmodified ZL107 has been compared.The wear resistance of as-cast ZL107 aluminum alloy can be significantly improved after modification. | WAN Diqing Key Laboratory of the Ministry of Education of China for Conveyance and Equipment,East China Jiaotong University,Nanchang 330013,China | 2010 | Rare Metals2010，29，5： | 2 |

| 16 | Microstructures and Morphology Evolution of Icosahedral Phase of As-cast Mg_(67.4)Zn_(28.9)Y_(3.7) Ternary Alloy Subjected to the Pouring Temperature显示文摘The microstructure,chemical composition and morphology evolution of icosahedral quasicrystalline phase of Mg67.4Zn28.9Y3.7 ternary alloy were investigated in detail at different pouring temperatures by X-ray diffraction(XRD),scanning electron microscopy(SEM) and energy-dispersive spectrum(EDS).Low interfacial energy favors the formation of I-phase.The experimental results show that the primary I-phase reveals petal-shaped with five and six branches,where each branch has facetted growth morphology with the size ranging from 50 to 100 μm.As the temperature decreases,the polygon-shaped I-phase forms,attributed to the decomposition of branch of petal-shaped I-phase,and then it grows bigger and some of the fine polygons join together to form large polygons.Besides these,(α-Mg+I-phase) eutectic structures disappear and the relative amount of Mg7Zn3 phase increases as the pouring temperature decreases.The chemical composition and morphology evolution of I-phase were also discussed. | Man Zhu Gencang Yang Diqing Wan Suling Cheng Yaohe Zhou | 2009 | Journal of Materials Science & Technology2009，25，4： | 1 |
