Effects of drying and wetting on extractable aluminum in strongly acid soils and in aluminum-saturated clays

Geoderma, 1973
Abstract A number of field-moist strongly acid soils, NaObr-treated soils, and Al-saturated clays were subjected to drying and wetting treatments in the laboratory. Oven drying of samples resulted in decreases in extractable Al and increases in extractable H from field-moist soils containing more than 12 mequiv./100 g exchange acidity and from Al ...

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.

The relationship of soil ph to aluminum saturation and exchangeable aluminum in ultisols and oxisols

Communications in Soil Science and Plant Analysis, 1986
Abstract For soil acidity assessment purposes, the relationship of either percent Al saturation or exchangeable Al to water pH is often misleading for tropical soils. Published data from studies using Ultisols and Oxisols were used to determine whether relationships between Al saturation or exchangeable Al and pH in 1M KCl and pHo are better criteria ...

Low Temperature Dehydration Kinetics of Aluminum‐ and Calcium‐saturated Soil Clays

Soil Science Society of America Journal, 1987
Abstract The kinetic parameters of the isothermal dehydration of standard bentonitic and soil clays with montmorillonitic, mixed, illitic, and kaolinitic mineralogy were studied under Al and Ca saturation. The isothermal temperatures employed under a constant water vapor pressure of

Saturation controlled softening/hardening in pure aluminum processed by surface rotation rolling

Scripta Materialia, 2020
Abstract Surface rotation rolling (SRR) treatment has been applied to cold-rolled and fully-annealed commercial-purity aluminums to refine the microstructure at the surface region. The treatments result in a strengthening in the as-annealed aluminum but a softening in the cold-rolled one.

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 ...

Saturation of normal-mode coupling in aluminum-oxide-aperture semiconductor nanocavities

Journal of Applied Physics, 2001
The photon density required for the saturation of normal-mode coupling in oxide-apertured nanocavities is measured to be 90 photons/μm2 by pump-probe experiments. The photon number is only 300 for a semiconductor nanocavity with a 2 μm diameter aluminum-oxide aperture, drastically reduced from 200 000 for a 50 μm waist on a planar microcavity.

Saturation magnetization and magnetostriction of Ni3Mn alloys containing aluminum and copper

Soviet Physics Journal, 1981
An experimental investigation was made into the influence of the addition of copper and aluminum on the saturation magnetization Js and magnetostriction λs of the Ni3Mn alloy. It is shown that the behavior of Js and λs depends on the distribution of the atoms of the added element over the sites of the fcc lattice of the Ni3Mn alloy.

Deposition and Dissolution of Lithium‐Aluminum Alloy and Aluminum from Chloride‐Saturated LiCl ‐ AlCl3 and NaCl ‐ AlCl3 Melts

Journal of The Electrochemical Society, 1981
Metal deposition‐dissolution studies in the melt were conducted primarily on an aluminum substrate, using the techniques of cyclic voltammetry, chronoamperometry, chronocoulometry, and chronopotentiometry. A lithium‐aluminum alloy was deposited. The alloy is formed predominately by a deposition process on the surface of the aluminum substrate rather ...

Internal Magnetic Fields and the Saturation Magnetization of Iron—Aluminum Alloys

Journal of Applied Physics, 1963
Internal magnetic fields in several iron—aluminum alloys ranging in composition from 19 to 28 at. % aluminum have been measured in a Mössbauer absorption experiment. In the composition range 22% to 26% aluminum three distinct internal magnetic fields were observed. At 300°K the magnitudes of these fields are in the ratio 1.00:0.88:0.72.
