Interface as typical planar defect in solids forms between two spatial regions occupied by different matter or by matter in different physical states. With reducing characteristic dimension of each matter, the density of interfaces increases. Especially nanostructured materials contain much high density of interfaces, and mechanical properties and other functionalities are heavily related to interfaces. An interface may be in thermal equilibrium or non-equilibrium depending on formation conditions. Correspondingly, an interface may possess multiple structures with different compositions, and thus exhibits various thermomechanical properties. Especially for ultra-fine and nanoscale structural materials, tailoring interface complexities has been demonstrated to be a powerful strategy in realizing unusual thermos-mechanical properties and other functionalities of materials. For example, interfacial segregation may change the elastic stress field and local chemical bonding along an interface. Atomic structures, excess free volume, and energy state of the interface consequently impact defect-interface interactions. Tailoring interfacial defects can mediate deformation modes, such as twinning, phase transformation, and dislocations because interfacial defects act as nucleation sources.
Of interest in this symposium are experimental and computational studies that probe:
i) Interface kinetics associated with the formation and evolution of interface structures and compositions
ii) Structures and energetics of characteristic interfaces
iii) Interface-dominated phenomena during interface formation
iv) Defects-interface interactions
v) Interface-mediated deformation mechanisms
vi) Interfacial segregation and Interface-assisted precipitation
vii) Interface stability (structure and composition) at extreme deformation, high temperature, and ion irradiation |
