Atomic configurations in P phase Cu-Al-Ni, Cu-Au-Zn and Cu-Zn-A1 ternary alloys before and after martensitic transformations, and occupancy sites of third elements X in the B2 parent lattice of Ti-Ni-X ternary alloys, where X = 3d elements, Pd and Au, have been investigated by means of an electron chanueling enhanced microanalysis method, called ALCHEMI. Large increases in M, and A, temperature...

Results are presented for a ductile metal reinforced bulk metallic glass matrix composite based on glass forming compositions in the Zr-Ti-Cu-Ni-Be system. Primary dendrite growth and solute partitioning in the molten state yields a microstructure consisting of a ductile crystalline Ti-Zr-Nb beta phase, with bcc structure, in a Zr-Ti-Nb-Cu-Ni-Be bulk metallic glass matrix. Under unconstrained m...

Time-resolved ellipsometric measurements were made upon Au, Cu, Ag, Ni, Pd, Ti, Zr, and Hf thin films. Using an elliptically polarized pump beam, the decay of the optically induced polarization of the sample was observed. Characteristic relaxation times are extracted and interpreted in terms of scattering of linear and angular momentum of hot electrons. A systematic variation is observed betwee...

The phase structures and hydrogen storage properties of a Ti Zr V Ni alloy are studied. It is found that this alloy consists of a 0.7 0.2 0.1 matrix and a secondary phase. The matrix is a B2-type compound with bcc structure and the secondary phase is a C14-type Laves phase with hexagonal structure. This alloy electrode has a larger charge–discharge capacity than stoichiometric TiNi electrodes b...

Three different Ti-based alloys with bcc structure and Laves phase were studied. The TiCr 1.1 V 0.9 , TiCr 1.1 V 0.45 Nb 0.45 and TiCr 1.1 V 0.9 + 4%Zr 7 Ni 10 alloys were melted in arc furnace under argon atmosphere. The hydrogen absorption capacity was measured by using aparatus type Sievert’s. Crystal structures, and the lattice parameters were determined by using X-ray diffraction, XRD. Mic...

The structural composition and electrochemical capacity of four AB2 Laves-type intermetallic alloys with various Ti/Zr ratios (TixZr1?xLa0.03Ni1.2Mn0.7V0.12Fe0.12, x = 0.12, 0.15, 0.18, 0.22) were investigated in this study. characterized by X-ray diffraction, scanning electron microscopy energy dispersive spectroscopy. These data revealed the coexistence main phase C15-type FCC compounds a sec...

The electrochemical capacity, hydrogen absorbed/desorbed activation properties of alloy Zr(Mn0.1V0.3Ni0.6)2 were improved after Ti substitution for the Zr. The microstructure of Zr12xTixsMn0.1V0.3Ni0.6d2 sx ­ 0, 0.5d alloys was analyzed by x-ray diffraction (XRD), transmission electron microscopy (TEM), and energy dispersive spectrum (EDS) analysis. A systematic structural analysis shows that t...

The kinetics of hydrogen absorption by magnesium bulk is affected by two main activated processes: the dissociation of the H2 molecule and the diffusion of atomic H into the bulk. In order to have fast absorption kinetics both activated processed need to have a low barrier. Here we report a systematic ab-initio density functional theory investigation of H2 dissociation and subsequent atomic H d...

The microstructure and electrochemical properties variation of alloy Zr(MnVNi)2 after Ti substitution for Zr was investigated. The microstructures of Zr1ÿxTix (MnVNi)2 (x = 0, 0.5) alloys were determined with X-ray di€raction (XRD), transmission electron microscopy (TEM), high resolution electron microscopy (HREM) and energy dispersive spectrum (EDS) analysis. The systematic structural analysis...
