Semi-solid Constitutive Parameters and Failure Behavior of a Cast AA7050 Alloy

Subroto, Tungky; Eskin, Dmitry G.; Miroux, Alexis; Ellingsen, Kjerstin; M'hamdi, Mohammed; Katgerman, Laurens (Journal article; Peer reviewed, 2021)

AA7050 is an aluminum alloy with superior mechanical properties; however, it is prone to hot tearing (HT) during its production via direct-chill casting. This study focuses on extracting constitutive parameters of the alloy ...
Towards 3D Modelling of Macrosegregation Formation and Modification in DC Casting of Aluminium Alloys Accounting for Equiaxed Grain Growth and Transport

Pakanati, Akash (Doctoral theses at NTNU;2019:34, Doctoral thesis, 2019)

Macrosegregation refers to the inhomogeneous distribution of solute elements at the scale of cast product. It is a severe defect affecting the quality of cast product produced through Direct Chill (DC) casting process. ...
