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, ...
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 ...
Temperature Dependece of the Elastic Constants of Aluminum
(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 ...
Temperature Variation of the Elastic Constants of Cubic Elements. I. Copper
(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 ...
The composite piezoelectric oscillator is employed to measure the adiabatic elastic moduli of crystalline aluminum over the temperature interval 63°K to 773°K.
(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 ...
Multivariate Analysis of High Through-Put Adhesively Bonded Single Lap Joints: Experimental and Workflow Protocols - Full report
(2016-06-07)
An adhesively bonded single lap joint was used to study the effects of coupon thickness, bondline thickness, surface preparation, presence of an overflow fillet, and adhesive type. Gains in the Education of Mathematics and ...
