Due to a viscoelastic damping middle layer,sandwich structures have the capacity of energy consumption.In this paper,we describe the frequency-dependent propert
A new model was established to calculate the real vapor pressure of Al in the molten Ni-xAI (at. Pct) (x=25~50)alloy. The effects of the holding time, chamber pr
The density functional theory, simplified by the local density approximation and mean-field approximation, is applied to study the surface properties of pure no
The dendrite growth process during the solidification of the Al-4.5 %Cu binary alloy was simulated using the phase-field model, proposed by Kim et al. Solute di
A series of samples of alumina-siloxane gel wrapped by poly(methyl methacrylate)and doped with rare earths such as lanthanum,praseodymium,yttrium,gadolinium and
The nanosized particle materials of doped-TiO2 with Y2O3 were prepared by means of sol-gel technique for use in electrorheological(ER)fluids,and their crystal s
A series of bulk ceramic samples of La1-xCaxMnO3 and Y1-xCaxMnO3 was prepared by the conventional solid state reaction method,and the samples of x=1/3 were inve
Surface passivation methods for porous Si (PS) surfaces, I.e., depositing diamond film or diamond-like carbon (DLC)film on PS surfaces, were attempted. Two emis
The effect of Pd addition on the glass-forming ability and thermal stability of the Zr5sAl10Cus0Nis-xPdx (x=0, 1, 3,5 at. Pct) alloys upon copper-mold casting h
