Examination of Ni-base superalloy diffusion couples containing multiphase regions
(2014-04-02)
Four Ni-base superalloy diffusion couples with multiphase regions were studied. The diffusion couples contained single-phase (gamma ), two phase( gamma +MC carbide) and three-phase ( gamma + gamma prime+MC carbide) ...
Al-Co-W 900C Phase Equilibria Data
(2014-09-03)
Phase equilibria at 900 °C in the Co-rich Co-Al-W ternary system are investigated through isothermal annealing of six alloy compositions for times up to 8000 h. The volume fraction of the L12-γ′ phase co-existing with ...
Measurement of Equilibrium Concentrations of Vacancies in Copper
(2014-07-02)
The net added fraction of thermally-generated atomic sites, ΔNN, has been measured, during equilibrium heating to near the melting point, in a coarse-grained copper bar of 99.999% purity. The linear thermal expansion, ΔLL, ...
Lattice Parameters, Densities, Expansion Coefficients and Perfection of Structure of Cu and Cu-In alpha Phase
(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 ...
Nature of Long-Range Order in Cu3+xAu1-x
(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 ...
Multivariate Analysis of High Through-Put Adhesively Bonded Single Lap Joints: Experimental and Work Flow Protocols - Analysis results
(2016-03-24)
Formatted categorical and numerical variables for multivariate analysis
Thermal Dilation of Copper
(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 ...
Temperature Dependence of the Elastic constants of Cu, Ag, and Au above Room Temperature
(1966-02-16)
The adiabatic elastic constants C44, 1/2(Cll-C12), and 1/2(cll+C12+2c44) have been measured for copper,
silver, and gold over the temperature range from 300° to about BOO 0K using the conventional ultrasonic
pulse-echo ...
The Relation Between Bulk Modulus and Relative Enthalpy: a Broad-Based Thermodynamic Analysis and a Case Study on Aluminum
(2001-07-17)
By postulating a linear relationship between logarithmic bulk modulus and relative enthalpy, we have developed in this
paper a thermodynamic framework that provides a link between thermal properties and bulk modulus under ...
Measurment of Equilibrium Concentrations in Aluminum
(1959-07-31)
Measurements of change in length and change in lattice parameter were made at identical temperatures on 99.995% aluminum in the temperature range 229 to 656°C. Length changes, ΔL, were measured on an unconstrained horizontal ...
