Measurement of Equilibrium Concentrations of Vacancies in Copper
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 Dependece of the Elastic Constants of Aluminum
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 ...
The High Temperature Elastic Moduli of Aluminum
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 ...
Temperature Variation of the Elastic Constants of Cubic Elements. I. Copper
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.
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 ...
Annealing Kinetics of Voids and the Self-Diffusion Coefficient in Aluminum
The annealing kinetics of voids in 99.9999 wt% pure aluminum were studied over the temperature range 85 to 209 °C in thin specimens by transmission electron microscopy. The isothermal shrinkage of individual voids was ...
Self-diffusion in aluminum at low temperatures
Values of the self-diffusivity of pure aluminum in the temperature range 130∮ to 200° have been determined by measuring the rate of annealing of prismatic and faulted dislocation loops in thin foils of quenched 99.999 pct ...
Multivariate Analysis of High Through-Put Adhesively Bonded Single Lap Joints: Experimental and Workflow Protocols - Full report
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 ...
Multivariate Analysis of High Through-Put Adhesively Bonded Single Lap Joints: Experimental and Work Flow Protocols – Constitutive mechanical properties
Tensile stress-strain mechanical test results and analysis for the adhesives and aluminum adherend.
