| 1 | A settling curve modeling method for quantitative description of the dispersion stability of carbon nanotubes in aquatic environments显示文摘Understanding the aggregation and deposition behavior of carbon nanotubes(CNTs) is of great significance in terms of their fate and transport in the environment. Attachment efficiency is a widely used index for well-dispersed CNT solutions. However, in natural waters, CNTs are usually heterogeneous in particle size. The attachment efficiency method is not applicable to such systems. Describing the dispersion stability of CNTs in natural aquatic systems is still a challenge. In this work, a settling curve modeling(SCM) method was developed for the description of the aggregation and deposition behavior of CNTs in aqueous solutions. The effects of water chemistry(natural organic matter, p H, and ionic strength) on the aggregation and deposition behavior of pristine and surface-functionalized multi-walled carbon nanotubes(MWCNTs) were systematically studied to evaluate the reliability of the SCM method. The results showed that, as compared to particle size and optical density, the centrifugal sedimentation rate constant(ks) from the settling curve profile is a practical, useful and reliable index for the description of heterogeneous CNT suspensions. The SCM method was successfully applied to MWCNT in three natural waters.The constituents in water, especially organic matter, determine the dispersion stability of MWCNTs in natural water bodies. | Lixia Zhou Dunxue Zhu Shujuan Zhang Bingcai Pan | 2015 | Journal of Environmental Sciences2015，27，3： | 4 |

| 6 | ANOMALOUS STRAIN RATE DEPENDENCE OF FLOW STRESS IN TiAl INTERMETALLIC COMPOUNDS显示文摘Plastic deformation of TiAI and TiAI-V intermetallic compounds has been studied by com-pression experiment at various temperatures and strain rates.Results show that the plasticdeformation in distinct temperature range is principally controlled by the mechanisms ofPeierls-Nabarro,cross slip and creep of dislocations.For TiAI-V alloy deformed at a rangeof 600—700 K,the negative strain rate dependence of flow stress was observed,i.e.,the morethe plastic strain is.the more the negative dependence will be.A possible mechanism of theanomaly could be interpreted by thermal activation of dislocation cross slipping.The effects oftemperature and strain rate on work-hardening exponent were also studied and discussed. | WANG Liming ZHU Dong YAO Mei CAI Qigong ZOU Dunxu State Key Laboratory for Fatigue and Fracture of Materials,Academia Sinica,Shenyang Central Iron and Steel Research Institute,Ministry of Metallurgical Industry,Beijing,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，5： | 1 |

| 8 | Microstructure Study of Ti-24Al-14Nb-3V Alloy显示文摘The microstructure of Ti-24Al-14NB-3V intermetallic alloy with solution treated was investigated by trans mission electron microscopy (TEM) and selected area electron diffraction (SAD) in conjunction with X-ray energydispersive spectroscopy (EDS) techniques. It shown that =50% ductile βo-phase and small amount of O phase,and α2 with the number of dislocations having c-component resulted in increasing slip system of the material, havecontributed to a good combination of strength and ductility at room temperature. Owing to some reciprocal planes ofsimilarity between α2 and O Phases, to distinguish both of two phases, a series of diffraction patterns obtained bytilting around one reciprocal direction of the phase are needed based on the systematic extinction and reciprocalplanes sequences occurred in the diffraction patterns, if those patterns are not containing one of three reciprocal unitvectors, a*, b*, c* in terms of the crystal unit cell, a, b, c. | MIAO Baihe LI Shiqiong BAI Yuanqiang ZHANG Jianwei ZOU Dunxu(Department of Materials Science and Engineering, USTB, Beijing 100083, China)(Department of Superalloys, Central Iron and Steel Research Institute, Beijing 100081, China) | 1997 | International Journal of Minerals,Metallurgy and Materials1997，11，1： | 0 |
| 9 | Microstructure and Mechanical Properties of TiAl-based Alloy显示文摘Two phases gamma titanium aluminide alloy,Ti-46.5Al-2.5V-1Cr.was investigated to characterizemicrostructures and to define the microstructure/mechanical property relationship.Many kinds ofmicrostructure of gamma and α2 phases were obtained by heat treatments in the α+γ,α2+γ and αfields.The effects of microstructure on tensile properties,fracture toughness and J-R resistancecurve at room temperature,were systematically studied.The experimental results showed that themicrostructure had a strong effect on mechanical properties,The duplex microstructure produced byheat treatment at 1250℃×4 h with controlled cooling resulted in the highest ductility of 4.8% tensileelongation,low fracture toughness and crack growth resistance.The fully lamellar microstructureproduced by heat treatment in the α field having large grain sizes resulted in the highest fracturetoughness but the lowest ductility. | Zhongjie PU Jiandong SHI Dunxu ZOU Zengyong ZHONG Central Iron and Steel Research Institute,Beijing,100081,China | 1993 | Journal of Materials Science & Technology1993，9，6： | 0 |
