  • Nix, F. C.; MacNair, D. (1941-08-08)
    Extremely accurate determinations of the linear thermal expansions have been made interferometrically from — 196°C to temperatures about +400°C for Al and +700°C for Fe, Ni, Cu and Au. The relationship between true thermal ...
  • Eppelsheimer, D.S.; Penman, R. R. (1950-01-07)
    The prediction that certain cubic metals may not be precisely cubic throughout a range of temperature below their melting points led to the present investigation. Pure copper was chosen as the cubic metal to examine for ...
  • Sutton, Paul M. (1953-04-28)
    The composite piezoelectric oscillator is employed to measure the adiabatic elastic moduli of crystalline aluminum over the temperature interval 63'K to 773 K. The data permit a valid extrapolation to O'K. The Debye ...
  • Overton, W.C.; Gaffney, John (1954-09-08)
    The ultrasonic pulse technique has been used in conjunction with a specially devised cryogenic technique to measure the velocities of 10-Mc/sec acoustic waves in copper single crystals in the range from 4.2°K to 300°K. The ...
  • Gerlich, D; Fisher, E.S. (1968-11-04)
    Measurements of the elastic moduli of aluminum over the temperature range 300°–930°K are reported. These data together with those reported for T < 300°K, show that all elastic moduli, including the shear moduli, vary ...
  • Straumanis, M. E.; Yu, L. S. (1969-04-08)
    Spectroscopically pure Cu has a lattice parameter a25 = 3.61491 Å (corrected for refraction), and a thermal expansion coefficient [alpha] = 14.87 × 10-6°C-1 between 15 and 55°C. The measured density d25 is 8.9314 ± 0.0002 ...
  • Tallon, J.L.; Wolfenden, A. (1979-03-02)
    The single crystal elastic constants of aluminum have been measured using a piezoelectric composite oscillator from room temperature to just 20K below the melting point. The elastic moduli differ markedly from previous ...
  • Ansara, I; Dinsdale, AT; Rand, MH (1998-07)
    Bearing in mind the alloy categories defined by industrial partners at the beginning of the Action, a matrix was drawn up to define the binary systems forming the building blocks for the evaluation of higher-order systems. ...
  • Gehlen, P. C.; Cohen, J. B. (2003-11-17)
    The diffuse scattering and intensities of Bragg peaks from single crystals of Cu77Au23 and Cu78Au22 have been studied for various degrees of long‐range order. The results indicate that the excess Cu atoms, replacing Au in ...
  • Doak, Jeff W.; Wolverton, C. (2012-10-15)
    Nanostructures formed by phase separation improve the thermoelectric figure of merit in lead chalcogenide semiconductor alloys, with coherent nanostructures giving larger improvements than incoherent nanostructures. However, ...
  • Tavazza, Francesca (2013-01-31)
    Under tensile deformation, Au nanowires (NWs) elongate to form single atom chains via a series of intermediate structural transformations. These intermediate structures are investigated using static density functional ...
  • Burton, Benjamin P. (2013-01-31)
    First principles phase diagram calculations were performed for the wurtzite-structure quasibinary systems AlN–GaN, GaN–InN, and AlN–InN.
  • Dupin, N.; Ansara, I.; Sundman, B. (2013-01-31)
    A re-assessment of the ternary system A1-Cr-Ni following Dupin's thesis work using a single Gibbs energy function for the gamma and gamma prime phases is presented taking into account new experimental liquidus temperatures. ...
  • 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 ...
  • Campbell, C.E. (2013-02-11)
    This work presents the assessment of the diffusion mobilities in both the γ′ (Ni3Al-L12) and B2 (NiAl) phases in the Ni–Al–Cr system utilizing the phenomenological model developed by Helander and Ågren. Available experimental ...
  • Chang, Keke; Du, Y.; Sun, W.H.; Xu, Honghui; Zhou, L.C. (2013-03-28)
    The V–Zn system was investigated by a combination of CALPHAD modeling with key experiments and first-principles calculations. Based on a critical literature review, one diffusion couple and nine alloys were designed to ...
  • Durga, A.; Kumar, K.C. (2013-03-28)
    The constitutional and thermochemical information of the Co–Zr system is modelled using the Calphad method to obtain a reliable thermodynamic description of the system. Appropriate sublattice models are chosen to describe ...
  • Du, Z.; Li, C. (2013-03-28)
    The Mg–Sm, Gd–Sm and Gd–Mg–Sm systems were thermodynamically optimized using the CALPHAD technique. The solution phases, liquid, bcc, hcp and rhombohedral, were described by the substitutional solution model. The isostructural ...
  • Du, Y.; Liu, Y.Q. (2013-03-28)
    he Cr–Ge binary system was thermodynamically optimized using the CALPHAD method. The liquid phase was described by means of an associate solution model. The BCC terminal solid solution was described by the substitutional ...
  • Sundman, Bo; Ohnuma, Ikuo; Dupin, Nathalie; Kattner, Ursula R; Fries, Suzana G. (2013-03-28)
    The Al–Fe system is important for many alloys and the new interest in iron aluminides makes it necessary to improve the modeling of the different ordered forms on the body-centered cubic lattice in this system. This has ...
