Behaviour of Al-Mg alloys at high temperature
TLDR
In this article, the behavior of a few Al-Mg alloys (up to 7.1 wt% Mg) has been studied on heating in air at 500°C for 8 h or more.Abstract:
The behaviour of a few Al-Mg alloys (up to 7.1 wt% Mg) has been studied on heating in air at 500°C for 8 h or more. The precipitation of a spinel phase, MgAl2O4, is found to take place on the surface and along the transverse section (depth) of the specimen. The alloys seem to be resistant to internal oxidation below 4.5% Mg and thereafter prone to it. Beryllium modification does not suppress the progress of internal oxidation taking place in the Al-Mg alloys. The results have been interpreted on the basis of anodized photomicrographs and X-ray diffraction data.read more

High-temperature oxidation of Al-Mg alloys
TL;DR: The effect of the atmosphere on the oxidation rates of aluminum-can alloy was studied using thermogravimetric methods as mentioned in this paper, and the results showed that the reduction of free oxygen in the atmosphere reduced the rate of oxidation.

XPS studies of oxide growth and segregation in aluminium-silicon alloys
TL;DR: In this paper, the oxidation of three aluminium-silicon alloys has been studied as a function of temperature and it was concluded that at temperatures in excess of 473 K magnesium segregation controls oxide growth and also that the degree of segregation is temperature dependent.

Surface chemistry of water atomised aluminium alloy powders
TL;DR: In this paper, the surface oxides of water atomised (WA) aluminium powders were characterized as a function of technological regimes (atomisation temperature and water pressure) by AES, showing that powders at higher water pressure are usually less oxidised than those atomised at a lower pressure.

The dragging of small oxide particles by migrating grain boundaries in copper
M.F. Ashby,R.M.A Gentamore +1 more
TL;DR: In this article, the authors show that grain boundaries, introduced into a copper single crystal by indenting and annealing the crystal, are shown to drag certain small (4000 A diameter) oxide particles with them when they migrate.
