Positron annihilation,TEM,SEM and high purity high pressure hot charging of hydrogen have been used to investigate the effect of microstructure,changed by varying of Ti content, on the hydrogen performance of the Fe-Ni-Co based alloys.It was found that th

The anistropy of interface kinetics is one of the important characteristic of the solid / liquid interface which plays a very important role on the interface stability and momhological evolution during solidification. Up to now no nature model has been es

Nanocrystalline Fe73.5 Cu1Nb3Si13.5B9 and Fe91Zr7B2 alloys were prepared by annealing amorphous ribbons above crystallization temperatures.The thermal expansion curves of as-quenched and annealed samples were measured in the temperature range of 100 to 90

As a functional material,TiNi alloy possesses several speific properties, but it is relatively difficult to Produce TiNi alloy foils because of its complicated processing and low product ratio.In this paper.a new process of making TiNi alloy foils, i.e.

Influences of annealing time for recrystallization texture of 70-30 brass rolled by cross shear rolling are investigated by the three dimensional orientation distribution function. It is found that in every layer there is a macroscopic statistic unsymmetr

Deformation-induced - continuous recrystallization (DICR) was revealed in a warm rolled Al-8Mg-0.2Zr alloy during initial stage of superplastic deformation. The mechanical behavior and microstructure of alloy change obviously before and after the completi

The surface of Mo is nitrided by multipulse laser irradiation in N2 ambient, leading to formation of γ-Mo2N phase in the nitrided surface. The laser pulses melt the irradiated sufaee to initiate nitridation reaction through a liquid phase. The nitride lay

An amorphous alloy of single phase could be prepared by mechanical alloying for the nominal composition of Fe60B40 which could hardly be formed by the rapid solidification of molten alloys,while nanocrystalline alloys would be produced in the other compos

X-ray diffraction, transmission electron microscopy and hardness measurement were used to study the mechanical alloying of Al-Ti system. It is found that Al-15at.-%Ti exhibits supersaturated structure after ball milling for 40h. Besides forming Al(Ti) for

In this paper, the tribological properties of R.F. sputtered MoS2 and WSZ thin solid film lubricant with grease 'were investigated on a ball-on-disc machine. The composition of films was analysed byXPS, SEM and EDX. The results show that the coefficient o

In this paper. the functionally gradient iron nitrides thin films were prepared by facing targets sputtering. Rutherford backscattering spectrometry (RBS) demonstrates that the concentration of Fe or N atoms varies gradually from the substrate to the surf

The phase transition temperature of Pb(Zn1/3Nb2/3)O3 -BaTiO3 (PZN-BT) system ceramics decreases sharply with the addition of BT content. This behavior is different from that of other ferroelectric solid-solutions. Based on the assumption of nano-phase sep

Since Bi-substituted YIG thin films,such as (BiAI)YIG thin film, have large Faraday rotation, they are widely used for magneto -optic waveguide applications. As an importmant magnehc anisotropy, the growth-induced magnetic anisotropy in (BiAI)YIG films ha

The efficiency of extractive boron(EEB)is directly related to the precipitating characteristics of the B component in the slags.The EEB is high if the B comPOnent existed in the crystal form of 2MgO·B2P3,otherwise the EEB is low in the form of amorphous p

PT ultrafine Powders dispersed in SiO2 (PT / SiO2) were prepared by two step hydrolysis method. Si(OC2H5)4 was at first partically hydrolyzed by dropping it into a mixed solution of H2O, C2H5OH and HCl for first hydrolysis 1 hour. The resultant homogeneou

PLZT(28 / 0 / 100) polycrystalline thin films (PLT 2B for short) on quartz glass and p-(1 1 1) Si substrates have been prepared by spinning method, the preferential oriented thin films of epitaxial growth on SrTiO3 and α- A12O3 single crystal substrates h

The titanium dioxide (TiO2) colloidal solutions were obtained by hydrolysis of tetrabutyi htanate. The transparent TiO2 membrane of thickness 1 μm was prepared by spreading colloidal particles on a conducting glass support. Atomic force microscope analysi

In this peper,the investigation of oxygen carries. which arc very important for the facilitated transport membraned(FTM)for enrichment of oxygen. were reviewed.The structure and it's influences on the oxygen transport propefties of three kinds of oxygen c

The effect of interface interaction of (Al18B4O33)w / ZL109 Al composite on the impact properties of the composite was studied.The results indicate that the degree of the interface interaction can be changed by changing the squeeze-casting temperature.The
