Premature melt solidification during mold filling and its influence on the as-cast structure

M. WU, M. AHMADEIN, A. LUDWIG

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 1, Pages 53-65 doi: 10.1007/s11465-017-0437-y

Abstract:

Premature melt solidification is the solidification of a melt during mold filling.this study, a numerical model is used to analyze the influence of the pouring process on the premature solidificationsolid crystals in the melt at the end of pouring are used as the initial conditions for the subsequent solidificationA five-phase volume-average model for mixed columnar-equiaxed solidification is used for the solidificationbetween the simulation and experimental results is achieved by considering the effect of premature melt solidification
