| 1 | ON THE BURN RESISTANCE OF Ti-35V-15Cr-0.05C TITANIUM ALLOY显示文摘The Ti-35V-15Cr-0.05C (wt% is a new nonburning titanium alloy. The test for alloy combustibility was carried out by using CO2 laser. A 430 watt and 6mm diameter laser spot impinges directly on the sample within normal atmospheric pressure and temperature. The results show that the ignition time of the nonburning titanium alloy is the longest in the eight examined titanium alloys, and is 3.5 times that of TC4 alloy. The ignition tempeerature of the nonburning alloy is 2991° C, and is higher than that of TC4 alloy by 1976°C. On the condition of high tempeerature and rich oxygen,the surface of alloy forms a melting layer which plays roles of oxygen insulation, heat insulation and burning products insulation. This is the mechanism of combustion resistance. | G.P.Li D.Li Y.Y.Liu Q.J.Wang S.X.Guan Q.C.Li | 1998 | Acta Metallurgica Sinica(English Letters)1998，11，3： | 2 |

| 3 | New ductile laminate structure of Ti-alloy/Ti-based metallic glass composite with high specific strength显示文摘Bulk laminate structure of Ti-alloy/Ti-based metallic glass composite(MGC) was prepared by melting a preform of alternate stack-up foils in the high vacuum atmosphere. The composite demonstrates a good combination of yield strength(~1618 MPa), plasticity(~4.3%) and specific fracture strength(384 × 10~3 Nmkg^(-1)) in compression. The maintained yield strength results from the unique microstructure composed of the Ti layer, the solution layer with gradient structure and the MGC layer. Such a multilayer structure effectively inhibits the propagation of shear band, leading to the enhanced plasticity. Those extraordinary properities suggest that combining ductile lamella with brittle metallic glass(MG) by such a lay-up method can be an effective way to improve mechanical properties of MG. | D.Li Z.W.Zhu A.M.Wang H.M.Fu H.Li H.W.Zhang H.F.Zhang | 2018 | Journal of Materials Science & Technology2018，34，4： | 2 |
| 4 | On generalised and specialised spatial information grids: are geo-services ready?显示文摘After the set-up of a spatial data infrastructure(SDI)and a national information infrastructure(NII)in many countries,the provision of geo-services became one of the most important and attractive tasks.With the integration of global positioning system(GPS),geographic information system(GIS)and remote sensing(RS),we can,in principle,answer any geo-spatial related question:when and where what object has which changes?An intelligent geo-service agent could provide end-users with the most necessary information in the shortest time and at the lowest cost.Unfortunately there is still a long way to go to achieve such goals.The central component in such geo-services is the integration of the spatial information system with a computing grid via wire-and wireless communication networks.This paper will mainly discuss the grid technology and its integration with spatial information technology,expounding potential problems and possible resolutions.A novel categorising of information grids in the context of geospatial information is proposed:generalised and specialised spatial information grids. | D.Li | 2008 | International Journal of Digital Earth2008，1，4： | 2 |
| 5 | Nd-RICH PHASE PARTICLES IN AS-FORGED Ti-5Al-4Sn-2Zr-1Mo-0.25Si-1Nd ALLOY显示文摘TEM examination proves that the second phase particle within the as-forged Ti-55alloy consists of either bright or dark 'matrix' (nano-Nd3Sn) and some small dark blocks (SnO) dispersed in the 'matrix'. The HREM observation shows that the nanoNd3Sn phase is roughly spherical and about 3-15nm in diameter, and the grain boundaries with atout 1nm width are 'gas-like' structure. | G.P.Li D.Li Y.Y.Liu S.X.

| 6 | NUCLEATION OF RARE EARTH-RICH PHASE PARTICLES IN Ti-5Al-4Sn-2Zr-1Mo-0.25Si-1Nd ALLOY显示文摘High resolution electron microscopy studies of rure earth-rich phase particles in a melt-quenched Ti-5Al-4Sn-2Zr-1MO-0.25Si-1Nd alloy indicate that the α-Ti matrix crystallizes prior to the rare earth-rich phase particles. According to a new nucleation model, the heteropeneous nucleation of the rare earth-rich phase particles at the matrix interface is easier than the homogeneous nucleation off the interface matrix, which is consistent with the results of the HREM obseroations. | G.P.Li D.Li and Y.

| 7 | Dynamic simulation based method for the reduction of complexity in design and control of Recirculating Aquaculture Systems显示文摘In this work we introduce the“Extensible Fish-tank Volume Model”that can reduce the complexity in the design and control of the Recirculating Aquaculture Systems.In the developed model we adjust the volume of a single fish-tank to the prescribed values of stocking density,by controlling the necessary volume in each time step.Having developed an advantageous feeding,water exchange and oxygen supply strategy,as well as considering a compromise scheduling for the fingerling input and product fish output,we divide the volume vs.time function into equidistant parts and calculate the average volumes for these parts.Comparing these average values with the volumes of available tanks,we can plan the appropriate grades.The elaborated method is a good example for a case,where computational modeling is used to simulate a‘‘fictitious process model”that cannot be feasibly realized in the practice,but can simplify and accelerate the design and planning of real world processes by reducing the complexity. | M.Varga S.Balogh Y.Wei D.Li B.Csukas | 2016 | Information Processing in Agriculture2016，3，3： | 1 |
