Crystallographic relationships of T-/S-phase aggregates in an Al-Cu-Mg-Ag alloy
Jonas K. Sunde, Duncan N. Johnstone, Sigurd Wenner +3
T-(Al20Cu2Mn3) phase dispersoids are important for limiting recovery and controlling grain growth in Al-Cu alloys. However, these dispersoids can also reduce precipitation hardenin…
The evolution of precipitate crystal structures in an Al-Mg-Si(-Cu) alloy studied by a combined HAADF-STEM and SPED approach
Jonas K. Sunde, Calin D. Marioara, Antonius T. J. van Helvoort +1
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 st…
Quantitative strain analysis of InAs/GaAs quantum dot materials
Per Erik Vullum, Magnus Nord, Maryam Vatanparast +5
Geometric phase analysis has been applied to high resolution aberration corrected (scanning) transmission electron microscopy images of InAs/GaAs quantum dot (QD) materials. We sho…
Bandgap measurement of high refractive index materials by off-axis EELS
Maryam Vatanparast, Ricardo Egoavil, Turid W. Reenaas +3
In the present work, Cs aberration corrected and monochromated scanning transmission electron microscopy electron energy loss spectroscopy STEM-EELS has been used to explore experi…
Assessing electron beam sensitivity for SrTiO and LaSrMnO using electron energy loss spectroscopy
Magnus Nord, Per Erik Vullum, Ingrid Hallsteinsen +2
Thresholds for beam damage have been assessed for LaSrMnO and SrTiO as a function of electron probe current and exposure time at 80 and 200 kV acceleration…
Cluster interactions for fcc-based structures in the Al-Mg-Si system
Nils Sandberg, Mattias Slabanja, Randi Holmestad
A class of proposed coherent precipitate structures (Guinier-Preston zones) in the Al-Mg-Si alloy are investigated using first-principles density functional theory methods. The clu…
