The Hall-Petch relationship holds true for a wide range of grain sizes, from coarse-grained materials down to nanocrystalline materials. However, there are some notable effects at different grain size ...

And methods that focus on reducing the materials’ grain size (to hamper effects like dislocation slip ... the team measured stress-strain curves that show a markedly higher yield strength for ...

Existing 3D printing techniques for calcium phosphate structures are limited to 120 micrometers in resolution—too coarse to replicate bone's microscopic framework. This technical limitation restricts ...
