Ultrasonic wave propagation in water-saturated aluminum foams

Ultrasonics, 1998
Abstract In this paper, we present an experimental study of ultrasonic wave propagation in water-saturated cellular aluminum foams using the pulse transmission method. The aluminum foam samples have an essentially open cell structure with fixed cell size and structure, but different porosities (from 88% to 95%).

Effect of Aluminum on the Saturation Moments of Fe-Ni Alloys

Journal of Applied Physics, 1967
The saturation magnetizations of Ni-Fe-Al terminal solid solution alloys have been measured by a force method. Field intensities up to 12.5 kOe were applied and the temperature of the specimens varied from room temperature to 8°K. Average atomic magnetic moments were calculated from values of σ∞,0 which were obtained by customary extrapolation ...

The interfacial tension between aluminum and cryolite melts saturated with alumina

Metallurgical Transactions B, 1977
A Method was developed for measuring the capillary depression of Met.allic aluminum in an alumina tube in a cryolite melt. As the tube was progressively lowered through the melt into the Met.al the volume of gas expelled was measured by the movement of a meniscus of liquid in a horizontal glass tube.

Solubility and Hydrolysis of Aluminum in Soil Solutions and Saturated‐paste Extracts

Soil Science Society of America Journal, 1970
Abstract Three Coastal Plains soils that had exhibited different “critical” pH values for maximum cotton yields in field experiments were analyzed for Al solubility. Fertilized soil was used to verify critical pH by a root‐growth experiment in a growthchamber and to obtain displaced soil solutions (⅓‐bar moisture)

Complex bulk modulus measurement of fluid-saturated porous aluminum

The Journal of the Acoustical Society of America, 1984
In the application of fluid-saturated porous materials to the absorption of sound it is assumed that the attenuation is enhanced by increased relative velocity between the solid matrix and the fluid. Foamed metals are expected to have a structure that is more rigid than that of other porous materials with larger concomitant absorption. The bulk modulus

Large Saturation Absorption of Resonant Aluminum Metasurfaces

CLEO 2024
We experimentally demonstrate that an aluminum metasurface is prospective saturable absorber with significant modulation depth (9.56%) under a low incident fluence of 25 μJ/cm2, due to local-field enhancement by surface lattice resonance in the near-infrared.

Internal stress measurments during the saturation fatigue of polycrystalline aluminum

Materials Science and Engineering, 1982
Abstract The internal stress and the effective stress were measured using stress relaxation techniques for 99.988% purity polycrystalline aluminum containing a well-defined cellular dislocation microstructure characteristic of large amplitude low cycle fatigue.

The Corrosion of 1100 Aluminum in Oxygen-Saturated Water at 70°C

Journal of The Electrochemical Society, 1963
In oxygen-saturated distilled water at 70 deg C, the rate and amount of corrosion of aluminum during short exposure are influenced by experimental conditions. One effect is that contamination of the water by the reaction increases the corrosion rate. Subsequent to the first several days, the amount of corrosion varied with the logarithm of the exposure
