Microscope-Bright Field (TEM-BF) image of triangular B2 precipitate (with flat interfaces and an average size of ~1.4 μm) in FCC matrix ). The precipitate morphology of B2 phase may be explained in terms of the competing energetic contributions of (i) strain energy, and (ii) interfacial energy during the growth (of the precipitate). For instance, the point at which the interfacial energy contribution predominates over strain energy contribution, is largely system-dependent ). This is highly essential for designing microstructures where precipitate morphology largely influences the mechanical properties of the material .
