The experiment studied the surface hardening effect of AgCu sheet through impact loading of explosion.The relation curve of the explosive impact load on different unit area AgCu sheet and surface hardening degree was established by the gradient arranging explosive test method.The main indexes of surface hardness,wear…
Carbon aerogel(CA) spheres were fabricated by inverse suspension/emulsion polymerization of resorcinol-formaldehyde aqueous solution,and then drying under ambient pressure,and finally carbonization under N2 atmosphere.The CA spheres were made into the electrodes of supercapacitors,and their electrochemical properties…
This article deals with the present situation of development of bamboo furniture design and the advantages existing in the development,then raises some strategies for bamboo furniture design based on the present society of low carbon economy.
In conventional industrial production of WC powders,there is an obstinate concept,which alleges the quality of WC powders will be better if fewer mixtures of tungsten and carbon powders are loaded.In the present paper,the effects of raw materials loaded in graphite boat on the energy consumption and the rate of carbon…
Implementing chemistry pretreatment and cellulase treatment on bamboo fiber for modification,the morphology and internal structure changes of treated bamboo fibers were studied by SEM,FTIR,WAXS and other experimental techniques.The results showed:cellulase treatment cut off and restored the cellulose molecular chain t…
Microstructural features of two oxide dispersion strengthened(ODS) ferritic steels by mechanical alloying using pure metal powders and nitrogen atomized powder as raw materials respectively were investigated.Microstructure analysis by SEM and X-ray diffraction,laser diffraction/scattering particle size distribution an…
Ultrafine Sr0.5Sm0.5CoO3 (SSC) ceramic powders with homogeneous composition were prepared via a low temperature combustion process and a coprecipitation process,respectively.The resultant SSC powders were characterized by X-ray diffraction,scanning electron microscope and energy dispersive spectroscope.The results sho…
The development trend of low temperature impact resistant ductile iron castings used for wind power generator was briefly described. Taking the ductile iron bearing seat casting as example, the production process key points of low temperature impact resistant ductile iron castings were introduced including:(1)it’s nec…
A new 1D chain coordination polymer [Pb(η2-FcL)2(phen)]n is obtained by slow evaporation of the solution, and characterized by the elemental analyses, 1H NMR, IR and thermogravimetric analysis. The crystal structure has been analyzed by X-ray diffraction. The title complex belongs to triclinic system with space group…
Fe nanoparticles prepared by sonochemical decomposition of Fe (CO)5 were heterogeneously precipitated onto the surface of SmCo5 powders to produce the SmCo5/Fe composite powders. The powders were sintered into bulk SmCo5/ α-Fe nanocomposite permanent magnets via spark plasma sintering (SPS). It was found that the rema…
Branched LiFePO4/C composites with carbon core structure were synthesized with epoxy resin as carbon source.LiFePO4/C composites were characterized by X-ray diffractometry(XRD),transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS),and their electrochemical properties were investigated in term…
Using fixed bed reactor,the process conditions for preparing styrene via ethyl benzene dehydrogenation with iron oxide as catalyst were studied.The product composition was determined by gas chromatography.The results showed that reaction temperature,feeding ratio and catalyst activity of ethyl benzene dehydrogenation…
The carbon fiber market is predicted to be around US$ 2 billion in 2010 with production of around 80 million lb. The major challenge for the carbon fiber manufacturing industry is cost effective production. With a decrease in cost,its usage will increase drastically. Carbon fiber can directly be prepared from PBO fibe…
A series of V-doped ZnO films was prepared using the radio-frequency magnetron sputtering.No secondary phases and metal clusters were found in either sample.All of the Zn1-xVxO films were single phase and c-axis preferred orientation.The XRD results also indicated a monotonic increased in the lattice constant with inc…
Through the finite element simulation on the Vickers indentation deformation of Zr55Al10Cu30Ni5 amorphous alloy by using DEFORM 3D software,the distribution of effective stresses and strains on the different regions in an indent are investigated.The results of simulation indicate that the effective stress and strain u…
