Fig. 3.6 Three possible spatial arrangements of a second phase, β (gray), in an α-phase (white) matrix. The dihedral angle θ between the phases (defined by the interfacial energies) defines the three-dimensional morphology. (a) θ > 60°, (b) θ < 60°, (c) θ = 0°. A careful analysis of two More

Fig. 9.50 Interaction between grain boundaries and second-phase particles. This interaction may be sufficient to balance the driving force for grain growth, stabilizing the grain size D is the diffusion coefficient and γ is the interfacial energy. Source: Adapted from Ref 7 More

Fig. 9.52 Volume fraction and size for typical second-phase particles in steels. Non-metallic inclusions (see Chapter 8, “Solidification, Segregation, and Nonmetallic Inclusions,” in this book) normally have a combination of size and distribution out of the region where second phase More
