Numerical investigations of freckles in directionally solidified nickel-based superalloy casting with abrupt contraction in cross section

Evolution of grain structure and formation of freckle defects were simulated in directionally solidified nickel-based superalloy casting with abrupt contraction in cross-section area. A two-dimensional (2D) Cellular Automaton (CA) – Finite Element (FE) model was presented. The transport of liquid mo...
