Effect of martensite embryo potency on the martensitic transformations in steels-A 3D phase-field study

► The embryo needs to be of a critical size in order to attain potency. ► Favorable shape of a martensite embryo is ellipsoidal. ► The orientation of the embryo also affects its potency. ► The dislocation density at the nucleation site affects the embryo potency.
