Aberration-Corrected STEM Study of Precipitates in an Al-Mg-Si-Ge-Cu Alloyon microscopy. The precipitates were needle or lath shaped with the longest dimension parallel to <001>.. The precipitates had no repeating unit cell when viewed along this direction. However, the precipitate structure in projection consisted of a hexagonal network of mixed Si and Ge columns, with M

Effect of Composition and Pre-Ageing on the Natural Ageing and Paint-Baking Behaviour of Al-Mg-Si AlSi) and an excess Si alloy (Al-0.5Mg-1.2Si) were cast and rolled to 1 mm thick sheet. Both were naturally aged for 30 days and then artificially aged for 0.5 h at 170°C to simulate an automotive body panel paint-baking cycle. In order to improve the paint-bake response, pre-ageing treatments of 20 s

Improvement in the Characterization of the 2099 Al-Li Alloy by FE-SEMinum-lithium alloy, and metallic alloys in general. Investigations were carried out on bulk and thinned samples. BSE imaging at 3kV and STEM imaging at 30kV along with highly efficient microanalysis permitted to correlate experimental and expected structures. Although our results confirm previous st

Towards new aluminium alloys through advances in atom probe microscopyding of microstructural properties. Today, alloy development has reached a level where many of these properties are no longer discussed on micrometre or even nanometre scale, but rather on atomic scale. Consequently, atom probe microscopy (APM) has received greatly increased attention. APM is a powe

Muon Spin Relaxation and Positron Annihilation Spectroscopy Studies of Natural Aging in Al-Mg-Si Allaluminium alloys. Positron annihilation spectroscopy (PAS) gives complimentary information about the electron density. We have conducted µSR and PAS experiments on an Al alloy with 1.07 at.% Mg and 0.53 at.% Si during natural aging after solution heat treatment. Three stages of positron lifetime cha
