Origin of the morphological change from rafted structure to irregular shape of the γ′ phase in single crystal nickel-based superalloys

Dependence of morphological evolution on the starting time of semi-coherency in semi-coherent interface model: (a) t* = 30,000, (b) t* = 80,000 and (c) t* = 150,000. (d) The coherent interface model. (t* = Dimensionless time.)99
