Dislocation–grain boundary interactions: Recent advances on the underlying mechanisms studied via nanoindentation testing
To comprehend the mechanical behavior of a polycrystalline material, an in-depth analysis
of individual grain boundary (GB) and dislocation interactions is of prime importance. In the …

Local analysis on dislocation structure and hardening during grain boundary pop-ins in tungsten
In the present work, dislocation structures at the grain boundary (GB) pop-in events were
studied around and below the Berkovich indentations using electron channeling contrast …

Indentation size effect in tungsten: quantification of geometrically necessary dislocations underneath the indentations using HR-EBSD
During indentation testing of the low defect density crystalline materials, higher hardness
values are found at lower indentation depths, which is referred to as an indentation size …
