Zinc coating is formed by the heterogeneous assembly of the Γ, Γ1, δ, ζ and η phases whose mechanical properties greatly differ from each other. Thermal strains resulting from large differences between thermal expansion coefficients are partially relaxed by the formation of a crack network. In order to model this phenomenon, initial hardness, thermal expansion coefficient αi and toughness (KIC)...

Certain cold-worked martensitic Ti-alloys exhibit tunable linear thermal expansion along a specific sample direction. These intriguing properties are related to the anisotropic of orthorhombic ?? martensite. However, tailored obtained in this way is limited single-phase temperature field , below reverse transformation martensite into austenite. Here, we demonstrate that iso formed by diffusion ...
