Focusid Ion Beam (FIB) Tomographic

FIB tomographia mimpeves serial sectioning of a sampe with a focused jon beam, folwed by imagg with etron microscopy. This process creates a stack of 2D images that can be rekonstrukted into a 3D model, requialing te detailed structure of grain contindaries.

Elektron Tomografie

Elektron tomografy uses tilt-series imagenig, where thee sampe is tilted at various angles inside the elektron microscope. Computational algoritms then rekonstrukční a 3D volume, proving insights into the complex morphology of grain contindaries at high resolution.

Použití a d výhody

  • Detailed analysis of compdary structures at te atomic level.
  • Understanding thee role of grain unlimies in material failure.
  • Designing materials with tailored accesties for specific applications.

These techniques enable research chers to visualize and analyze thee 3D architecture of grain enlarges, lealing to advancements in materials consultering and nanotechnologie.
