In recent years, near-nano (submicron) and nanostructured materials have attracted
increasingly more attention from the materials community. Nanocrystalline materials are …

One of the most dangerous technical failures of materials is intergranular brittle fracture
(temper embrittlement) as it proceeds very quickly and its appearance is often hardly …

We discuss theoretical models of interfacial embrittlement by solute segregation. Of
properties susceptible to alteration by segregation, the ideal work of interfacial separation …

Grain boundaries are important structural components of polycrystalline materials used in
the vast majority of technical applications. Because grain boundaries form a continuous …

The microstructure of commercially available nanocrystalline (nc) electroplated Ni foils is
studied by means of X-ray diffraction and transmission electron microscopy. It is shown that …

A new theory is presented to describe the segregation-induced changes in grain boundary
cohesion. This approach enables the changes to be calculated readily from tabulated …

Grain boundaries (GBs) play a crucial role in the mechanical behaviors of nanocrystalline
materials. The dynamics of GBs depend on a variety of intrinsic and extrinsic factors …

Physical and chemical properties of solid materials are strongly. influenced by the chemical
composition of internal interfaces, One of the crucial parameters affecting interfacial …

In this paper first a generally valid model is derived from the two fundamental equations of
Gibbs for temperature and composition dependences of all types of interfacial energies. This …

A new and a radically different mechanism to account for the beneficial effects that small
additions of elements such as yttrium have on the adherence of oxide scales is proposed. It …
