Scope Interfaces play an important role in determining several properties in multiphase systems. In a materials system, interfaces can be present across different length scales, some examples being:

(i) Nanoscale interphase interfaces in a precipitation hardened system,
(ii) Microscale interface across ceramic on metal or metal on metal builds; for example bond coat deposition on turbine blade, multilayer thin films and
(iii) Macroscale interfaces of joined similar or dissimilar materials; for example in brazing and soldering, transient liquid phase bonding,

Diffusive phase transitions across these metastable interfaces can be triggered via thermo-mechanical processing so as to achieve close to equilibrium structural/compositional/stress states. Renditions of time-dependent development of off-equilibrium interface structures have been accomplished through multiscale experimental and computational techniques that allow for identification of the positions of atomic columns and structural defects at the interface. The motivation of this symposium is to bring together such novel studies directed towards identifying phase transformation pathways across multiscale material interfaces.
