Activity Measurement of Silicon in Molten Cu-Si Binary Alloy

Texture of Cu and Dilute Binary Cu-Alloy Films:

The impact of 11 alloying elements, namely Mg, Ti, In, Sn, Al, Ag, Co, Nb and B, at two nominal concentration of 1 and 3 at.%, and Ir and W, at only a nominal concentration of 3 at.%, on the evolution of texture of Cu was investigated. The behavior of the alloy films was compared with that for pure Cu films. The films were electron beam evaporated onto oxidized Si wafers and had thicknesses in ...

Collective ionic dynamics in a molten binary alloy

A recent experiment @Phys. Rev. Lett. 80, 2141 ~1998!# showed heavily damped excitations in molten Li4Pb, within kinematic scales well beyond those of hydrodynamic sound. These findings pointed to the presence of short-lived out-of-phase atomic motions as the underlying microscopic phenomenon. A series of computer molecular dynamics studies are performed to investigate the details of the atomic...

THE INFLUENCE OF DRY SLIDING ON PRCIPITATION HARDENING BEHAVIORS OF Al-Cu-Si ALLOY

Abstract: Cold working performed before an aging treatment has a significant effect on size and amount of precipitate produced. This could be caused by the increase in defect density, such as vacancies and dislocations. In this research, the Al-Cu-Si alloy was solution-treated, wear-tested and then artificially aged for a period of 1–5 h. Changes in the amount of precipitate, in the lattice par...

Structure of molten Al and eutectic Al–Si alloy studied by neutron diffraction

Formation, Thermal Stability and Mechanical Properties of Cu-Zr and Cu-Hf Binary Glassy Alloy Rods

Glassy alloy rods with diameters up to 1.5mm exhibiting a large supercooled liquid region before crystallization and high mechanical strength were formed in Cu-Zr and Cu-Hf binary alloy systems by the copper mold casting method. The large supercooled liquid region exceeding 40K was obtained in the composition range of 30 to 70 at%Zr and 35 to 60 at%Hf. The largest value of the supercooled liqui...
