Precipitation behavior in an Al-Cu-Mg-Si alloy during ageing
(Peer reviewed; Journal article, 2019)The precipitation behavior and aging response of an Al-4.9Cu-0.74Mg-0.51Si-0.48Mn-0.1Cr-0.08Ti-0.02Fe (wt. %) alloy was examined in detail after aging at 170 °C with different dwell times up to 96 h. Deformation by ... -
Precipitation in an Al-Mg-Cu alloy and the effect of a low amount of Ag
(Journal article, 2016)Two high-purity aluminium alloys based on composition Al–3.0Mg–1.0Cu (wt%), one with added 0.4 wt% Ag, were compared up to 11 days ageing at 443 K by means of transmission electron microscopy and hardness measurements. The ... -
Soft particles assisted grain refinement and strengthening of an Al-Bi-Zn alloy subjected to ECAP
(Journal article; Peer reviewed, 2017)With the aim to improve the strength of potential Pb-free Al-Bi based bearing alloys, an Al-6Bi-8Zn alloy was subjected to equal channel angular pressing (ECAP). To reveal the roles played by the soft Bi particles, an ... -
Strengthening and toughening mechanisms of an ultrafine grained Mg-Gd-Y-Zr alloy processed by cyclic extrusion and compression
(Journal article; Peer reviewed, 2017)Cyclic extrusion and compression (CEC) was implemented to process the Mg-Gd-Y-Zr alloy. Microstructure characters, including the matrix grain, precipitates and texture evolution, were tried to correlate with the mechanical ... -
Strengthening mechanisms in ultrafine grained Al-Mg-Si alloy processed by hydrostatic extrusion – Influence of ageing temperature
(Journal article, 2016)Microstructure of hydrostatically extruded Al-Mg-Si alloy was studied by the combination of electron backscattered diffraction and transmission electron microscopy. Three different grain types which feature various defects ... -
Synergistic effects of Cd, Si and Cr additions on precipitation strengthening and thermal stability of dispersoids in AA3003 alloy
(Peer reviewed; Journal article, 2022)The thermally stable Mn-rich dispersoids in Al alloys were recently reported to have a significant dispersion strengthening effect. Further improvements in the dispersion strengthening and thermal stability of Mn-rich ... -
Synergistic strengthening by nano-sized α-Al (Mn, Fe) Si and Al3Zr dispersoids in a heat-resistant Al–Mn–Fe–Si–Zr alloy
(Peer reviewed; Journal article, 2021)Strengthening by dispersoids in Al alloys has been limited by either low number density or low volume fraction of dispersoids. In the present work, the influence of an addition of 0.28 wt% Zr on precipitation hardening ... -
The effect of alloying elements on the ductility of Al-Mg-Si alloys
(Journal article; Peer reviewed, 2017)Experiments were conducted to document the combined effect of different alloying elements on the microstructure and associated stress-strain behavior of extruded Al-Mg-Si alloys, with a special emphasis on the ductility ... -
The effect of silicon on the strengthening and work hardening of aluminum at room temperature
(Journal article; Peer reviewed, 2013)Solution hardening of Al–Si alloys at room temperature was investigated by tensile tests of several aluminum alloys containing various amounts of Si in solution but fabricated from the same commercially pure base material. ... -
The effects of quench rate and pre-deformation on precipitation hardening in Al–Mg–Si alloys with different Cu amounts
(Journal article, 2014)The effects of quench rate after solution heat treatment in combination with 1% pre-deformation on precipitation hardening in three Al–Mg–Si alloys have been investigated by transmission electron microscopy and hardness ... -
The influence of microchemistry on the softening behaviour of two cold-rolled Al-Mn-Fe-Si alloys
(Journal article, 2014)The influence of microchemistry on the softening behaviour of two cold-rolled Al–Mn–Fe–Si alloys with different initial amounts of Mn (0.4 and 1.0 wt%) is studied. In addition to their as-cast conditions, the supersaturated ... -
Through thickness variations of deformation texture in round profile extrusions of 6063-type aluminium alloy: Experiments, FEM and crystal plasticity modelling
(Journal article; Peer reviewed, 2018)The deformation texture and its through-thickness heterogeneity for an extruded round profile are experimentally measured by the electron back-scatter diffraction technique (EBSD), and numerically modelled by coupling FEM ...
