Controlling grain structure and texture in Al-Mn from the competition between precipitation and recrystallization
Huang, Ke; Zhang, Kai; Marthinsen, Knut; Loge, RE (Journal article; Peer reviewed, 2017)The recrystallization behaviour of Al-Mn alloys (AA3xxx series alloys) is affected by randomly distributed dispersoids present before annealing, by dispersoids precipitated at grain/subgrain boundaries before the onset of ... -
Correlating oriented grain number density of recrystallisation in particle-containing aluminium alloys
Zhao, Qinglong; ZHANG, Hui-di; Huang, Ke; Marthinsen, Knut (Journal article; Peer reviewed, 2018)The recrystallized grain structure of Al–(Mn)–Fe–Si alloys after isothermal annealing was studied by electron backscatter diffraction (EBSD) technique. Statistical correlation suggests that the frequency of forming P-oriented ... -
Evolution in microstructure and properties during non-isothermal annealing of a cold-rolled Al-Mn-Fe-Si alloy with different microchemistry states
Huang, Ke; Engler, Olaf; Li, Yanjun; Marthinsen, Knut (Journal article, 2015)The softening behaviour during non-isothermal annealing of a cold-rolled Al–Mn–Fe–Si model alloy was studied as a function of the state of microchemistry, in terms of the solute level of Mn, size and spatial distribution ... -
Isothermal and non-isothermal annealing of cold-rolled Al-Mn-Fe-Si alloys with different microchemistry states
Huang, Ke; Li, Yanjun; Marthinsen, Knut (Journal article, 2014)Investigation of the microstructural evolution of Al-Mn-Fe-Si alloys during annealing after cold rolling has been carried out. The effect of microchemistry state in terms of Mn in solid solution, constituents, size and ... -
Isothermal annealing of cold-rolled Al−Mn−Fe−Si alloy with different microchemistry states
Huang, Ke; Li, Yanjun; Marthinsen, Knut (Journal article, 2014)Microstructural evolution of a cold-rolled Al–Mn–Fe–Si alloy during annealing was studied. Except the as-cast variant, two other different homogenizations were considered, one gave a high density of fine dispersiods providing ... -
Microstructural evolution during isothermal annealing of a cold-rolled Al-Mn-Fe-Si alloy with different microchemistry states
Huang, Ke; Li, Yanjun; Marthinsen, Knut (Journal article, 2014)In this paper, investigations of the softening behaviour of a supersaturated Al-Mn-Fe-Si alloy during annealing after cold rolling have been carried out. Two different homogenization conditions were considered, of which ... -
Modelling microstructure and properties during annealing of coldrolled Al-Mn-Fe-Si-alloys with different microchemistries
Marthinsen, Knut; Wang, Ning; Huang, Ke (Journal article, 2014)The physical basis and a mathematical formulation of a softening model nicknamed Alsoft, accounting for the combined effect of recovery and recrystallization during annealing of heavily deformed aluminium alloys have been ... -
Modelling the evolution in microchemistry and its effects on the softening behavior of cold rolled AlFeMnSi-alloys during annealing
Hersent, Emmanuel C; Huang, Ke; Friis, Jesper; Marthinsen, Knut (Journal article, 2013)A dedicated diffusion controlled precipitation model for AlMnFeSi-alloys, based on classical nucleation and growth theory, has been implemented and coupled to a phenomenological softening model accounting for the combined ... -
The double-edge effect of second-phase particles on the recrystallization behaviour and associated mechanical properties of metallic materials
Huang, Ke; Marthinsen, Knut; Zhao, Qinglong; Loge, Roland E. (Journal article; Peer reviewed, 2018)Most industrial alloys contain a matrix phase and dispersed second-phase particles. Several thermomechanical processing (TMP) steps are usually needed to produce a final product, during which recrystallization and its ... -
The influence of microchemistry on the softening behaviour of two cold-rolled Al-Mn-Fe-Si alloys
Huang, Ke; Wang, Ning; Li, Yanjun; Marthinsen, Knut (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 ... -
The influence of processing conditions on microchemistry and the softening behavior of cold rolled Al-Mn-Fe-Si alloys
Wang, Ning; Huang, Ke; Li, Yanjun; Marthinsen, Knut (Journal article; Peer reviewed, 2016)Using different homogenization treatments, different initial microchemistry conditions in terms of solid solution levels of Mn, and number densities and sizes of constituents and dispersoids were achieved in an Al-Mn-Fe-Si ...
