Phase field study of acicular growth: Role of elasticity in Widmanstätten structure

A phase field model accounting for inhomogeneous and anisotropic elasticity has been developed to study the growth of acicular precipitates. The diffusion-controlled growth of an isolated precipitate is investigated in the presence of elastic stresses generated by anisotropic transformation eigenstr...
