Grain boundaries exhibit phase-like behavior in which their structure, chemistry and
properties may change discontinuously at critical values of thermodynamic parameters such …

Recent observations of three classes of nanometer-thick, disordered, interfacial films in
multicomponent inorganic materials are reviewed and critically assessed. The three classes …

Interfaces and the movement of atoms within an interface play a crucial role in determining
the processing and properties of virtually all materials. However, the nature of interfaces in …

This article reviews recent experimental and theoretical results that elucidate the mysterious
subsolidus activated sintering mechanism. A related new concept of liquid-like interface …

Catastrophic brittle fracture of crystalline materials is one of the best documented but most
poorly understood fundamental phenomena in materials science. Embrittlement of copper …

Structure and phase composition of five binary Al–Zn and Al–Mg alloys were studied before
and after high pressure torsion (HPT) with a shear strain 300. The grain size of (Al) solid …

The enhancement of material properties caused by extremely small grain sizes in metals
and ceramics is attractive for many technological applications including protective coatings …

Grain boundaries (GBs) can be treated as two‐dimensional (2‐D) interfacial phases (also
called “complexions”) that can undergo interfacial phase‐like transitions. As bulk phase …

Two types of alloys, Cu-Ni-Co-Si and Cu-Cr-Zr, are considered candidate materials for next-
generation integrated circuits due to their superior comprehensive performance. However …

Nickel-doped tungsten specimens were prepared with high purity chemicals and sintered.
Although activated sintering starts more than 400° C below the bulk eutectic temperature …
