  • Du, Zeting; Jing, Zhan-Peng; Li, Changrong; Niu, Chunji (2013-01-31)
    The energy expressions for GP zones in the Al–Ag binary system, including the ε-state and the η-state ones, are established by combining the essential Gibbs energy for the matrix alloy with the interfacial energy and the ...
  • Du, Y.; Liang, D.; Liu, Yajun; Sheng, G.; Wang, Jiang; Zhang, L. (2013-04-01)
    CALPHAD kinetics has evolved to be a well-established discipline, which allows complex non-equilibrium processes to be fully explored. Such a success relies on the use of Redlich–Kister polynomials to describe atomic ...
  • Du, Y.; Liang, D.; Liu, Y.; Sheng, G.; Wang, J.; Zhang, L. (2013-07-08)
    Diffusion in Ag-based solders is a practical topic that has attracted world-wide attention. With the available experimental data in the literature, the atomic mobilities of Ag, Cd and Sn in fcc Ag–Cd and Ag–Sn alloys are ...
  • Liu, X.J.; Shangguan, N.; Wang, C.P. (2013-03-30)
    Based on the available thermodynamic information and diffusion coefficient data of the Ag–Zn binary system, the atomic mobilities of Ag and Zn in face-centred cubic (fcc) Ag–Zn alloys have been assessed as a function of ...
  • Brennan, Sarah; Warren, Andrew P.; Coffey, Kevin R.; Kulkarni, Nagraj; Todd, Peter; Kilmov, Mikhail; Sohn, Yongho (2013-05-07)
    The diffusion of Al in polycrystalline Mg (99.9%) was studied via depth profiling with secondary ion mass spectrometry in the temperature range of 573-673 K, utilizing the thin film method and thin film solution to the ...
  • Desorbo, Warren; Turnbull, David (2013-09-30)
    It is shown that in very high-purity aluminum, Al_II, the rate of vacancy annealing depends on vacancy concentration and annealing temperature but is independent of the temperature T_i of vacancy injection per se. The rate ...
  • Rowland, T. J.; Fradin, F. Y. (2013-10-01)
    Using a radio‐frequency field pulse technique which enables measurement of slow atomic diffusion by means of nuclear magnetic resonance we have obtained, for nominally 6–9's pure Al, an activation energy for self‐diffusion ...
  • Nowick, A.S. (2013-10-01)
    Torsion experiments on an aluminum‐zinc alloy (21 atomic percent zinc) show that precipitation gives rise to large values of internal friction. After prolonged periods of aging, which are sufficient to produce growth of ...
  • Rowland, T. J.; Fradin, F. Y. (2013-09-30)
    Using a radio‐frequency field pulse technique which enables measurement of slow atomic diffusion by means of nuclear magnetic resonance we have obtained, for nominally 6–9's pure Al, an activation energy for self‐diffusion ...
  • Slichter, Charles P.; Spokas, John J. (2013-09-30)
    Nuclear spin-lattice relaxation times T_1 and phase memory times T_2 have been measured in 99.99% pure aluminum foil from 77°K to the melting point by the spin-echo method. At high temperature the line narrows due to ...
  • Stoebe, T. G.; Gulliver, R. D.; Ogurtani, T. O.; Huggins, R. A. (2013-09-30)
    Motions1 narrowing of nuclear magnetic resonance lines is used to study self diffusion of aluminum in high purity aluminum and in solid solution alloys of aluminum with zinc. magnesium and copper. Diffusion parameters are ...
  • Seeger, A.; Wolf, D.; Mehrer, H. (2013-09-30)
    The various nuclear magnetic resonance techniques used for determining self-diffusion coefficients and activation energies in aluminium are evaluated critically. The data considered most reliable are analyzed together with ...
  • Beyeler, M.; Adda, Y. (2014-01-19)
    Self-diffusion of gold, copper and aluminium has been investigated for single crystals treated under pressures of 0 to 10 kbars in a temperature range of 700 °C to 990 °C for copper and gold and 400-610 °C for aluminium. ...
  • Messer, R.; Dais, S.; Wolf, D. (2014-01-19)
  • Lundy, T. S.; Murdock, J. F. (2013-10-01)
    Diffusion coefficients of Al^26 and Mn^54 in aluminum have been determined between 450° and 650°C. Low specific activities of the isotopes necessitated use of a thick layer technique. The exact solution to Fick's second ...
  • Campbell, Carelyn E.; Zhao, J-C.; Henry, M. F. (2013-05-05)
    A multicomponent diffusion mobility database for the Ni-rich fcc phase [2002Cam] is evaluated by comparing diffusion simulations to two experimental multicomponent Ni-base superalloy diffusion couples: Ni/Rene´-88 and ...
