In situ TEM study of twin boundary migration in sub-micron Be fibers
, 2015 Deformation twinning in hexagonal crystals is often considered as a way to palliate the lack of independent slip systems. This mechanism might be either exacerbated or shut down in small-scale crystals whose mechanical behavior can significantly deviate ...

Strain Gradient Plasticity Analysis of Amorphous Plasticity
Procedia Structural IntegrityAmorphous materials lack a defined crystalline structure, exhibiting a disordered atomic arrangement that imparts superb mechanical properties and great potential for applications in many areas. Because of their disordered nature, metallic glasses exhibit dramatically different deformation behaviours than crystalline materials.

Gradient microstructure formation in carbon steel bars
Journal of Materials Research and TechnologyIn recent years, severe plastic deformation has been one of the most popular methods of increasing the mechanical properties of bars. Obtaining an ultra or nanostructure in such bars provides high strength properties, but also reduces plasticity.
