Copper enrichment on aluminium surfaces after electropolishing and its effect on electron imaging and diffraction
(Peer reviewed; Journal article, 2020)Electropolishing is the most common method of preparing samples of aluminium alloys for scanning and transmission electron microscopy, as it yields a good surface quality and large flat, electron-transparent areas. Like ... -
The effect of low Cu additions on precipitate crystal structures in overaged Al-Mg-Si(-Cu) alloys
(Peer reviewed; Journal article, 2020)This study concerns the effect of low Cu additions (<0.1 at.%) on the precipitate crystal structure evolution in three Al-Mg-Si(-Cu) alloys during overageing. The evolution was assessed through a combination of atomic ... -
Grain boundary structures and their correlation with intergranular corrosion in an extruded Al-Mg-Si-Cu alloy
(Peer reviewed; Journal article, 2020)A detailed analysis of grain boundaries in a highly textured Al-Mg-Si-Cu alloy is presented in this work. Electron backscatter diffraction demonstrates the presence of three main categories of grain boundaries in addition ... -
A hybrid aluminium alloy and its zoo of interacting nano-precipitates
(Peer reviewed; Journal article, 2015)An alloy with aluminium as its base element is heat treated to form a multitude of precipitate phases known from different classes of industrial alloys: Al–Cu(–Mg), Al–Mg–Si–Cu, and Al–Zn–Mg. Nanometer-sized needle-shaped ... -
Lattice rotations in precipitate free zones in an Al-Mg-Si alloy
(Peer reviewed; Journal article, 2018)Scanning precession electron diffraction and automated crystal orientation mapping in a transmission electron microscope (TEM) have been applied to quantitatively study the crystal orientation of precipitate free zones ... -
Precipitate/matrix incompatibilities related to the {111}Al Ω plates in an Al-Cu-Mg-Ag alloy
(Peer reviewed; Journal article, 2021)The atomic structure of Ω plates forming on {111}Al planes in an Al-Cu-Mg-Ag alloy has been investigated by Z-contrast atomic-resolution scanning transmission electron microscopy imaging and ab initio density functional ... -
The evolution of precipitate crystal structures in an Al-Mg-Si(-Cu) alloy studied by a combined HAADF-STEM and SPED approach
(Journal article; Peer reviewed, 2018)This work presents a detailed investigation into the effect of a low Cu addition (0.01 at.%) on precipitation in an Al-0.80Mg-0.85Si alloy during ageing. The precipitate crystal structures were assessed by scanning ... -
A transmission electron microscopy study of precipitate phases that form during operation in a heat exchanger alloy
(Peer reviewed; Journal article, 2019)During manufacturing of heat exchangers, the core material is cladded with a lower-melting point alloy, rolled into thin strips before being formed and finally brazed at an elevated temperature. After a period of natural ...
