| 6 | THE INFLUENCE OF CAVITY DAMAGE ON MECHANICAL PROPERTIES OF SUPERPLASTICALLY-DEFORMED MATERIALS AND ITS PREDICTION显示文摘Aluminium alloy LY12CZ sheet without any pre-treatment has been used to study the influence of cavity damage on the mechanical properties of the superplastically-deformed materials room temper- ature. The experimental results show that: (1) the lower the rate of cavitation as the superplastic strain increases, the higher the superplasticity is; (2) the mechanical properties of superplastically- deformed materials at room temperature decrease as the superplastically-deformed strain increases, especially, a noteworthy decrease in elasticity modulus, yield strenth and ultimate strength at room temperature begins to appear as the level of cavitation by area comes up to about 4%, while at the same level the reduction in area drops down a very large quantity. Then, a three-layer back- propagation neural network has been developed to predict the machanichl properties of the superplasti- cally-deformed material.The results acquired from the neural network are very | M.

| 8 | INTERACTION OF PRECIPITATION AND RECRYSTALLIZATION IN RAPIDLY SOLIDIFIED Cu-Cr-Zr-Mg ALLOY显示文摘In this paper; the recrystallization process during aging for a rapidly solidified Cu-Cr-Zr-Mg alloy has been investigated. It is found that the discotinuous crystallization process has been partially retarded by the ultra-fine and dispersed precipitation upon aging after deformation. Thus, a phenomenon of combined in situ and discontinuous recrystallization has been observed in the rapidly solidified Cu-Cr-Zr-Mg alloy.On the nucleation and growth of recrystallization, the precipitated phases are coarscned and dissolved in the front of grain boundaries following a re-precipitation in the recrystallization area,which results in the much more dispersed precipitates. | Liu, P.

| 9 | ION HEATING PROCESS DURING PLASMA IMMERSION ION IMPLANTATION显示文摘The research on plasma immersion ion implantation has been conducted for a little over ten years. Much is needed to investigate including processing technlogy, plasma sheath dynamics, interaction of plasma and surface, etc. Of the processing methods elavated temperature technique is usually used in PIII to produce a thick modified layer by means of the thermal diffusion. Meanwhile plasma ion heating is more recently developed by Ronghua Wei et al[1]. Therefore the temeperature is a critical parameter in plasma ion processing. In this paper we present the theoretical model and analysize the effect of imlantation voltage, plasma density, ion mass,etc on the temperature rise. | X.B. Tian, X.F. Wang, A.G. Liu, L.P. Wang, S.

| 10 | New exact solutions for free vibrations of rectangular thin plates by symplectic dual method显示文摘The separation of variables is employed to solveHamiltonian dual form of eigenvalue problem for transversefree vibrations of thin plates,and formulation of the naturalmode in closed form is performed.The closed-form natu-ral mode satisfies the governing equation of the eigenvalueproblem of thin plate exactly and is applicable for any typesof boundary conditions.With all combinations of simply-supported(S)and clamped(C)boundary conditions appliedto the natural mode,the mode shapes are obtained uniquelyand two eigenvalue equations are derived with respect to twospatial coordinates,with the aid of which the normal modesand frequencies are solved exactly.It was believed that theexact eigensolutions for cases SSCC,SCCC and CCCC wereunable to be obtained,however,they are successfully foundin this paper.Comparisons between the present results andthe FEM results validate the present exact solutions,whichcan thus be taken as the benchmark for verifying differentapproximate approaches. | Y.

| 11 | LASER LIFT-OFF OF GaN THIN FILMS FROM SAPPHIRE SUBSTRATES显示文摘Gallium Nitride film was successfully separated from sapphire substrate by laser radiation. The absorption of the 248nm radiation by the GaN at the interface results in rapid thermal decomposition of the interfacial layer, yielding metallic Ga and N2 gas. The substrate can be easily removed by heating above the Ga melting point (29℃). X-ray diffraction, atomic force microscopy and Photoluminescence of CaN before and after lift-off process have been performed, which demonstrated that the separation and transfer process do not alter the structural quality of the GaN films. And further discussions on the threshold energy and crack-free strategies of laser lift-off process have also been presented. | J. Xu, R. Zhang, Y.P. Wang, X.Q. Xiu, S.L. Gu, B. Shen, Y. Shi, Z.G.

| 12 | MICROSTRUCTURE AND PROPERTIES OF HIGH BORON BEARING STEEL显示文摘High boron bearing steel, in which boron homogeneously distributed, was successfully produced in the vacuum induction furnace. The microstructural observations of cast and hot rolled steels showed that the addition of titanium can eliminate the quantity of ferrous borides precipitated at the grain boundaries and break the net microstructure, as a result, its hot workability is improved. The titanium boride TiB2 homogeneously distributes in the matrix of a-Fe. The parameters of hot rolling process. including preheated temperature, initial rolling temperature, finished rolling temperature and the total deformation, have been optimized. | C.S. Liu, S. Y.

| 14 | Geographical distribution of red and green Noctiluca scintillans显示文摘The dinoflagellate Noctiluca scintillans is one of the most important and abundant red tide organisms and it is distributed world-wide. It occurs in two forms. Red Noctiluca is heterotrophic and fills the role of one of the microzooplankton grazers in the foodweb. In contrast, green Noctiluca contains a photosynthetic symbiont Pedinomonas noctilucae (a prasinophyte), but it also feeds on other plankton when the food supply is abundant. In this review, we document the global distribution of these two forms and include the first maps of their global distribution. Red Noctiluca occurs widely in the temperate to sub-tropical coastal regions of the world. It occurs over a wide temperature range of about 10°C to 25°C and at higher salinities (generally not in estuaries). It is particularly abundant in high productivity areas such as upwelling or eutrophic areas where diatoms dominate since they are its preferred food source. Green Noctiluca is much more restricted to a temperature range of 25°C-30°C and mainly occurs in tropical waters of Southeast Asia, Bay of Bengal (east coast of India), in the eastern, western and northern Arabian Sea, the Red Sea, and recently it has become very abundant in the Gulf of Oman. Red and green Noctiluca do overlap in their distribution in the eastern, northern and western Arabian Sea with a seasonal shift from green Noctiluca in the cooler winter convective mixing, higher productivity season, to red Noctiluca in the more oligotrophic warmer summer season. | P.

| 16 | Effects of Boron Addition on Grain Refinement in TiAl-based Alloys显示文摘Solid state phase transformation characteristics of the body centred β(Ti) into the hexagonal closed packed α(Ti) in Ti45Al8Nb-(0, 0.3, 0.5 and 0.8 at. pct) B alloys were investigated by heat treatment to clarify γ/α2 lamellar microstructure refinement induced by B addition. Experimental results confirmed two kinds of boron-reduced grain refinement mechanisms through refining either β phase then α phase (β-refinement) or α phase directly (α-refinement) to refine lamellar microstructure at room temperature; however, the role of α-refinement dominated the as-cast lamellar microstructure refinement over β-refinement in Ti45Al8NbxB alloy. It was also found that during the α-refinement the convoluted flake- and plate-like borides along β grain boundaries assisted nucleation of α phase, and the particle-like borides near β grain boundaries impeded α phase growth. | W.D.

| 17 | The Characterization of Sputtered Zr-Ge-N Thin Films as Diffusion Barriers Between Copper and Silicon显示文摘The main purpose of the present micro-structural analysis by transmission electron microscopy(TEM)and X-ray diffraction(XRD)was to investigate whether amorphous Zr-Ge-N films are a potential candidate as a diffusion barrier for Cu wiring used in Si devices.The Zr-Ge-N films were prepared by a radio frequency(RF)reactive magnetron sputter-deposition technique using N2 and Ar mixed gas,and the film structure was found to be sensitive to the gas flow ratio of N2 vs.Ar during sputtering.Polycrystalline Zr-Ge-N films were obtained when the N2/(Ar+N2)ratio was smaller than 0.2 and amorphous-like Zr-Ge-N films were obtained when the ratio was larger than 0.3.Diffusion barrier test was performed by annealing the Cu/Zr-Ge-N/Si film stack under Ar atmosphere.The deposited Zr-Ge-N(C)films remained amorphous even after high temperature annealing.The Cu diffusion profile in the film was assessed by the Auger electron spectroscopy(AES).The results indicate that Cu diffusion was minimal in amorphous Zr-Ge-N(C)films even at high annealing temperatures of 800℃. | Yang, J.
