1. 1. Characterization of surface defects caused by ultrasonic cleaning of aluminium

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Emanuel Eriksson; [2022]
   Keywords : Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

   Abstract : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.

3. 2. Fatigue life validation of aircraft materials

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Aashish Ramesh; Gaurav Kalkur; [2020]
   Keywords : Fatigue; Failure; High strength aluminium; High strength steel alloy; Al 7050-T7451; Al 7075-T6; AISI 4340 steels;

   Abstract : Fatigue is one of the critical design aspects with immense significance where thefatigue life of a material can be stated as the number of cycles that a componentcan withstand under a particular type of loading without failure. The design processhas to include fatigue analysis in order to predict failure due to fatigue. READ MORE

4. 3. [87]Sr/[86]Sr in plagioclase, evidence for a crustal origin of the Hakefjorden Complex, SW Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Alexandra Glommé; [2015]
   Keywords : Plagioclase; Älgön; Sr-isotopes; Sweden; MC-ICP-MS; Hakefjorden complex; geochemistry; SEM; Earth and Environmental Sciences;

   Abstract : The studied intrusion, the Hakefjorden Complex on Älgön is a norite-anorthosite complex situated in the archipelago on the west coast of Sweden. The origin of the intrusion will be deduce through in situ Sr-isotope analysis by MC-ICP-MS (multiple collector- inductively coupled plasma- mass spectrometry) on plagioclase, together with petrographic description and chemical analysis.
