Grain boundaries can undergo phase-like transitions, called complexion transitions, in which their structure, composition, and properties change discontinuously as temperature, bulk composition, and other parameters are varied. Grain boundary complex

Grain boundaries and other interfaces can undergo complexion transitions from one thermodynamic state to another, resulting in discontinuous changes in interface properties such as diffusivity, mobility, and cohesive strength. The kinetics of such co

Nanocrystalline Ni–W alloys are reported in the literature to be stabilized against high temperature grain growth by W-segregation at the grain boundaries. However, alternative thermal stability mechanisms have been insufficiently investigated, esp

Ni-23 at.%W thin films were ion-beam machined and tested in bending. Microstructures were characterized with aberration-corrected electron microscopy and the fracture surfaces were inspected after each test with SEM. Nominally amorphous films were fr

Bulk phase transformation kinetics were not well understood before Davenport and Bain developed time–temperature-transformation (TTT) diagrams for steel alloys in the 1930s. These powerful diagrams revolutionized the heat treatment of steel and oth

Thermally activated processes such as diffusivity, grain growth, oxidation, and catalysis are often modeled using the Arrhenius equation, in which the steady-state process rate increases with increasing temperature, yielding a positive activation ene

The carbide Ni6W6C has been identified in electroplated and sputtered nanocrystalline Ni–23 at.% W annealed at 700 °C. This carbide is unexpected and forms due to carbon contamination, which is difficult to avoid in practice. Carbon has a low solu

Grain boundaries exhibit phase-like behavior in which their structure, chemistry and properties may change discontinuously at critical values of thermodynamic parameters such as temperature, pressure and chemical potential. Therefore, grain boundarie
