Precipitates in aluminium alloys – studied by advanced (S)TEM techniques
Scanning Precession Electron Diffraction to Aid Aluminum Alloy Development
Precipitates in aluminium alloys – studied by scanning transmission electron microscopy and diffraction
The Effect of Multiple Solute Species in Solute Strengthening in Aluminium Alloys - MD study
The strength of a metallic alloy is controlled by the collective contribution from different strengthening mechanisms. To develop a complete numerical framework for the flow stress in alloys, it is necessary to understand the different mechanisms isolated, as well as knowing how they interact and af...
Plasticity and dislocation mechanisms in aluminium alloys containing precipitate free zones
In situ heating TEM observations of evolving nanoscale Al‐Mg‐Si‐Cu precipitates
This research concerns the precipitation and subsequent dissolution of precipitate phases in an Al–0.86Mg–0.62Si–0.1Cu (at.%) alloy subjected to varying thermal exposure during an in situ heating transmission electron microscope (TEM) experiment. The distribution and crystal structure of precipitate...
Precipitation behavior in an Al-Cu-Mg-Si alloy during ageing
Corrosion Phenomena in Duplex Brasses Containing Aluminium
Grain boundary degradation phenomena in forged CW626N alloy containing aluminium, after exposition to corrosive environment according to standard NS-EN ISO 6509-1:2014, was systematically investigated by scanning/transmission electron microscopes. Already after three minutes exposure to CuCl2 aqueou...
Copper enriched by dealloying as external cathode in intergranular corrosion of aluminium alloy AA6005
The purpose of this work is to understand the role of Cu in the propagation mechanism of IGC on extruded alloy AA6005-T5. The constituent Cu segregates as a Cu-rich nanolayer, together with the formation of a solute depleted zone, along the grain boundaries during thermomechanical processing of the ...
