Orientation independent and dependent subgrain growth during iso-thermal annealing of high- purity and commercial purity aluminium
Bunkholt, Sindre; Nes, Erik; Marthinsen, Knut (Journal article; Peer reviewed, 2019)The orientation dependence on recovery has been studied in cold-rolled and annealed polycrystalline high-purity aluminium (99.99 wt%), binary Al-0.25Mn and commercial purity aluminium. The growth mechanisms were found to ... -
Recovery Kinetics in High Purity and Commercial Purity Aluminium Alloys
Bunkholt, Sindre; Marthinsen, Knut; Nes, Erik Aasmund (Journal article, 2013)Motivated by improving current softening models for recycle friendly alloys, softening was investigated in high purity and commercial purity aluminium alloys. Utilizing the electron backscatter diffraction (EBSD) technique, ... -
Softening Behaviour of Selected Commercially Pure Aluminium Model Alloys
Sande, Gunnar (Master thesis, 2012)A characterization of the softening behaviour of four different commercially pure aluminium alloys has been carried out. The work is related to the MOREAL project (Modelling towards value-added recycling friendly aluminium ... -
Subgrain Growth, Recovery Kinetics and Nucleation of Recrystallization of Cold Deformed Aluminium Alloys
Bunkholt, Sindre (Doktoravhandlinger ved NTNU, 1503-8181; 2013:330, Doctoral thesis, 2013)Phenomena related to annealing of aluminium alloys are among the least understood in aluminium metallurgy but very important for industrial thermo-mechanical processing i.e. deformation and annealing. Physical models are ... -
Subgrain structures characterized by electron backscatter diffraction (EBSD)
Bunkholt, Sindre; Marthinsen, Knut; Nes, Erik Aasmund (Journal article; Peer reviewed, 2014)Subgrain structures are frequently characterized by the electron backscatter diffraction (EBSD) method, which is both accurate and provides good statistics. This is essential to better understand the subgrain growth ... -
The effect of iron and the precipitation behavior of iron during annealing of a cold deformed commercial purity aluminium alloy
Bunkholt, Sindre; Nes, Erik Aasmund; Marthinsen, Knut (Journal article; Peer reviewed, 2017)Iron is always present in any aluminium alloy and usually as an impurity element. In commercial purity alloys the concentration of iron is typically so large that iron has a strong influence on the material properties, due ...
