Nanocrystalline metals are transitioning from laboratory curiosities to engineering materials,
in large part due to advances in improving their stability, making their exceptional properties …

Processing science for nanocrystalline metals has largely focused on far-from-equilibrium
methods that can generate many grain boundaries with excess defect energy. Conversely …

Porous metals are lightweight and multi-functional at the expense of strength and ductility,
requiring post-heat treatment to elevate mechanical properties. In this study, we report …

We present large-scale atomistic simulations that reveal triple junction (TJ) segregation in Pt–
Au nanocrystalline alloys in agreement with experimental observations. While existing …

Nanostructured materials, with average grain size in nanometer scale and a high volume
fraction of grain boundaries, were known to have advanced mechanical properties, such as …

A primary shortcoming of nanocrystalline materials is that they tend to coarsen at elevated
temperatures, which limits their practical application. Nowadays, it is crucial to develop a …

Non-isothermal oxidation behavior of Ni 50 Ti 49.6 V 0.4 (at.%) and Ni 50 Ti 46 V 4 (at.%)
polycrystalline alloys was investigated through thermogravimetric analysis. Differential …

Recent experiments show that super-elasticity degeneration occurs during the cyclic
deformation of polycrystalline NiTi SMAs and the extent of such degeneration depends …

The addition of a ternary solute to reduce the accompanying loss in hardness in a Ni-Cu-P
alloy is reported. Here, P serves as the stabilizing addition by its partitioning to the grain …

Grain boundary wetting by the melt in the Cu-10 wt.% Ag alloy The phase transformations
can proceed not only between bulk phases but also in free surfaces, grain boundaries and …
