Impact of inlet flow on macrosegregation formation accounting for grain motion and morphology evolution in DC casting of aluminium
Pakanati, Akash; Tveito, Knut Omdal; M'hamdi, Mohammed; Combeau, Hervé; Založnik, Miha (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2018)Several transport mechanisms contribute to macrosegregation formation in Direct Chill (DC) casting of aluminium. The latter include solidification shrinkage induced flow, thermal-solutal convection and grain motion. The ... -
Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
Pakanati, Akash; M'hamdi, Mohammed; Combeau, Hervé; Založnik, Miha (Peer reviewed; Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
A simplified three-phase model of equiaxed solidification for the prediction of microstructure and macrosegregation in castings
Tveito, Knut Omdal; Pakanati, Akash; M'hamdi, Mohammed; Combeau, Hervé; Založnik, Miha (Peer reviewed; Journal article, 2018)Macrosegregation is a result of the interplay of various transport mechanisms, including natural convection, solidification shrinkage, and grain motion. Experimental observations also indicate the impact of grain morphology, ...
