This paper is a study of the model constant of the Voller-Prakash model: the mushy zone constant (C), which determines the flow resistance in the mushy zone during metal solidification. A drag force-liquid fraction relation was derived, assuming that

Various defects are produced during the laser powder bed fusion (L-PBF) process, which can affect the quality of the fabricated part. Previous studies have revealed that the defects formed are correlated with molten pool dimensions. Powder particles

Melt pool dimensions (depth: D and width: W) are strongly correlated with defects generated in laser powder bed fusion. The melt pool dimensions have been evaluated by CFD simulation including solid–liquid–gas phase change and laser multiple refl

In this study, the solidification behaviors of Hastelloy X during laser powder bed fusion (LPBF) were deliberately changed by fabricating a sample with constricted geometry. In-situ temperature measurement by a high-speed thermographic camera and par

Recent years have witnessed increasing demand for selective laser melting (SLM) in practical applications; however, determining the appropriate process parameter range remains challenging. In this study, a framework was developed to determine the app
