Semi-quantitative determinations of silicon, magnesium, copper and iron in aluminum alloys

Ultralow Temperature Anelasticity of Aluminum-Magnesium Alloys

Results of internal friction measurements on the commercial aluminum-magnesium alloys 5052,5086 and 5486 are reported here over the temperature range 50 mK to 300 K, and compared with published data on alloy 5056. Effects of heat treatment and explosive bonds on the internal friction are evaluated. The quality factor of proposed multi-layer aluminum-alloy spherical resonant-mass detectors of gr...

Effect of Aluminum on the Microstructure and Mechanical Properties of Austempered Ductile Iron Alloys

Effect of Aluminum on the Microstructure and Mechanical Properties of Austempered Ductile Iron Alloys

Transferable local pseudopotentials for magnesium, aluminum and silicon.

One obstacle in orbital-free density functional theory (OF-DFT) is the lack of accurate and transferable local pseudopotentials (LPSs). In this work, we build high quality LPSs by inverting Kohn-Sham (KS) equations on bulk valence electron densities to obtain an atom-centered local pseudopotential. With this approach, we build LPSs for Mg, Al, and Si, and then test them in KS DFT calculations o...

USE OF 8 - HYDROXYQUINOLINE IN DETERMINATIONS OF ALUMINUM , BERYLLIUM , AND MAGNESIUM By Howard

The methods commonly used for precipitating aluminum by 8-hydroxyquinoline from an acetic-acid solution, buffered with ammonium acetate, do not sufficiently define the conditions requisite for complete precipitation. The present article describes a method in which aluminum is precipitated as the oxyquinolate from a solution which has been partially neutralized with ammonium hydroxide, using bro...
