To develop advanced materials, a deep understanding of their underlying microstructure and chemistry is necessary. Knowing how defects influence the interplay between microstructure and chemical ...

The orientations of these infinitesimally small separations between individual “grains” of a polycrystalline material have big effects. In a material such as aluminum, these collections of grains ...

The common engineering ceramic materials can be identified as Aluminium Oxide (Alumina), Silicon Carbide, Silicon Nitride, Sialon and Zirconia. These materials are classified as “Engineering” or ...

"We don't have many applications, industrially, of things where the pressures are as high as in these experiments, but by showing pressure is one way of suppressing grain boundary deformation we can ...

Using advanced microscopy coupled with novel computer simulations to track atomic movement, researchers conducted real-time atomic-level observations of grain boundary deformation in poly-grained ...

Grain boundaries are interfaces that separate different crystallographic regions, known as grains, within a polycrystalline material. In nanomaterials, grain boundaries play a crucial role in ...

Also known as 3D printing, additive manufacturing (AM) is a disruptive new manufacturing technique that is employed to create metallic parts with enhanced mechanical properties in contrast to other ...

(Top) Picture of thermal measurement setup in the Goodson lab, Stanford University. (bottom) The sample is placed on a high-precision stage and raster scanned to produce 2D images of the thermal ...

Results indicate that grain boundary strength and motion, accommodated by either shear-coupled migration (SCM) or grain boundary sliding (GBS), strongly varies with pressure resulting in grain ...

(Nanowerk News) Metallic materials used in engineering must be strong and ductile – capable of carrying high mechanical loads while able to withstand deformation without breaking. Whether a material ...
