Chemical Modification of Al-Mg2Si Eutectic With Additions of Calcium and Strontium
Linga, Håkon (Master thesis, 2020)Eutektiske og legeringer nær eutektisk komposisjon er vanlege å bruke til støping på grunn av ypperlige støpeegenskaper, og ein slik legering er Al-5Mg-2Si som danner ein stor andel av den eutektiske fasen Al-Mg2Si. Sjølv ... -
Clustering and Precipitation during Early-Stage Artificial Aging of Al–Si–Mg(–Cu) Foundry Alloys
Wenner, Sigurd; Hatzoglou, Constantinos; Mørtsell, Eva Anne; Åsholt, Petter (Peer reviewed; Journal article, 2023)High-Si aluminum foundry alloys are an important material class for products with complex 3D geometries where casting is the most suitable production method. With Mg and/or Cu additions, these alloys gain strength upon ... -
How Slight Solidification Rate Variations within Cast Plate Affect Mechanical Response: A Study on As-Cast A356 Alloy with Cu Addition
Di Giovanni, Maria Teresa; Cerri, Emanuela; Saito, Takeshi; Akhtar, Shahid; Åsholt, Petter; Li, Yanjun; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2018)The present work investigates a narrow range of secondary dendrite arm spacing (SDAS), in an as-cast A356 alloy with and without copper (Cu) additions. Cu was added to the base A356 alloy melt to reach the target concentration ...
