Effect of Coupling Low-Flow Pouring with Inoculation on the As-Cast Microstructure of 7055 Alloys
Achieving uniform grain size in ingots is challenging in traditional direct chill (DC) casting. The thermal conditions during solidification often result in smaller grain size at the edge of the ingot compared...

Constitutive Modeling and Activation Energy Maps for a Continuously Cast Hyperperitectic Steel
An appropriate experimental scheme and an accurate constitutive model are the two key factors that determine the success or failure of the constitutive equations used to simulate hot deformation behavior durin...

Four-Phase Dendritic Model for the Prediction of Macrosegregation, Shrinkage Cavity, and Porosity in a 55-Ton Ingot
A four-phase dendritic model was developed to predict the macrosegregation, shrinkage cavity, and porosity during solidification. In this four-phase dendritic model, some important factors, including dendritic...
