| 1 | Surface Characterization and Cell Response of Binary Ti-Ag Alloys with CP Ti as Material Control显示文摘In this study, the surface passive films, dissolution behavior and biocompatibility of Ti-Ag alloys (with 5%, 10% and 20% Ag) were evaluated by X-ray diffraction (XRD) tests, electrochemical corrosion tests, X-ray photoelectron spectroscopy (XPS) tests, dissolution tests and in-vitro cytotoxicity tests. The surface films on the Ti-20Ag alloy are rich in Ti and much deficient in Ag with respect to alloy composition, as identified by XPS. Compared to CP Ti, Ti-5Ag and Ti-20Ag alloys show larger impedances and lower capacitances, which can be associated with an increase of the passive layer thickness. Moreover, all Ti-Ag alloys exhibit negligible or low metal release in the test solutions. The in-vitro cytotoxicity results show Ti-Ag alloys seem to be as cytocompatible as CP Ti. From the viewpoint of surface passive film and cytotoxicity, Ti-5Ag and Ti-20Ag are considered to be more suitable for dental applications. | B.B. Zhang K.J. Qiu B.L. Wang L. Li Y.F.

| 2 | Constitutive equation and model validation for a 31 vol.% B_4Cp/6061Al composite during hot compression显示文摘An accurate constitutive equation is essential to understanding the flow behavior of B_4C/Al composites during the hot deformation. However, the constitutive equations developed previously in literature are generally for low strain rate deformation. In the present work, we modified the general constitutive equation and take the high strain rate correction into account. The constitutive equation for a31 vol.% B_4Cp/6061 Al composite was constructed based on the flow stresses measured during isothermal hot compression at temperatures ranging from 375 to 525?C and strain rates from 0.01 to 10 s-1. The experimental flow stresses were corrected by considering temperature-dependent Arrhenius factor. The modified equation was then verified by using DEFORM-3 D finite element analysis to simulate the experimental hot compression process. The results show that the modified equation successfully predicts flow stress, load–displacement, and the temperature rise. This helps to optimize the hot deformation process,and to obtain desirable properties, such as reduced porosity and homogenous particle distribution in B_4C/Al composites. | L. Zhou C. Cui Q.Z.

| 3 | Microstructural evolution of aluminum alloy during friction stir welding under different tool rotation rates and cooling conditions显示文摘The microstructural evolution during friction stir welding(FSW) has long been studied only using one single welding parameter. Conclusions were usually made based on the final microstructure observation and hence were one-sided. In this study, we used the 'take-action' technique to freeze the microstructure of an Al-Mg-Si alloy during FSW, and then systematically investigated the microstructures along the material flow path under different tool rotation rates and cooling conditions. A universal characteristic of the microstructural evolution including four stages was identified, i.e. dynamic recovery(DRV), dislocation multiplication, new grain formation and grain growth. However, the dynamic recrystallization(DRX)mechanisms in FSW depended on the welding condition. For the air cooling condition, the DRX mechanisms were related to continuous DRX associated with subgrain rotation and geometric DRX at high and low rotation rates, respectively. Under the water cooling condition, we found a new DRX mechanism associated with the progressive lattice rotation resulting from the pinning of the second-phase particles.Based on the analyses of the influencing factors of grain refinement, it was clearly demonstrated that the delay of DRV and DRX was the efficient method to refine the grains during FSW. Besides, ultra-high strain rate and a short duration at high temperatures were the key factors to produce an ultrafine-grained material. | X.H. Zeng P. Xue L.H. Wu D.R. Ni B.L. Xiao K.S. Wang Z.Y.

| 4 | INVESTIGATION ON THE FORMATION MECHANISM OF TITANIUM CARBIDE PREPARED BY IN SITU REACTION IN MOLTEN ALUMINUM显示文摘A novel technique m which TiC particulates are prepared by an in situ reaction in molten aluminum is introduced for producing TiC/Al composite. In order to reveal the characteristic of the technique, the formation mechanism of TiC particulates prepared by this method is studied in this paper. Both theoretical and experimental results have shown that the TiC particulates are formed by a diffusion mechanism when the molar fraction of aluminum in the preforms is higher than 20.02%. On the contrary, the TiC particulates are formed by a solution-precipitation mechanism when the fraction of aluminum in the preforms is lower than 20.02%. | Yang, B. Wang, Y.Q Zhang, J.

| 11 | EFFECTS OF TREATMENT TEMPERATURE ON THE MICROSTRUCTURE AND MAGNETIC PROPERTIES OF Fe-N THIN FILMS显示文摘Fe-N thin films were fabricated on both 100Si and NaCl substrates by RF magnetron sputtering under low nitrogen partial pressure. The microstructure and magnetic properties of Fe-N thin films were investigated with the increase of the substrate temperature (Ts) and the annealing temperature (Ta). It is more difficult for nitrogen atoms to enter the Fe lattice under higher Ts above 150℃. The phase evolution is visible at higher Ta above 200℃. The phase transformation of α''-Fe16N2 occurred at 400℃. The change of crystal size with Ta was clearly visible from bright and dark field images. The clear high-resolution electron microscope (HREM) images of 110α, 111γ', 112α'', and 200α'' phases were observed. The interplanar distances from TEM (transmission electron microscope) and HREM match the calculated values very well. From the results of the vibrating sample magnetometer (VSM), the good magnetic properties of Fe-N films were obtained at 150℃ of Ts and 200℃ of Ta, respectively. | B.L. Li H.M. Du X.F. Wang E.Y.
