Bruker Nano Analytics presents:

In-situ SEM Nanoindentation Combined with 3D EBSD

On-Demand Session - 44 Minutes

Nanomechanical Testing and Electron Backscatter Diffraction Analysis

Nanoindentation is a well-established technique for assessing the mechanical properties of a material/sample with respect to its microstructure. This applies to heterogenous materials with microscale anisotropy given by the crystallographic texture that influences the onset of crystal plasticity and deformation process.

Bruker’s unique ability to combine nanomechanical testing instruments and EDS/EBSD detectors for Scanning Electron Microscope (SEM) allows researchers to comprehensively investigate the composition, microstructure and understanding of the deformation mechanisms of materials at the sub-micron scale.

PI 89 SEM PicoIndenter: Rotation and Tilt stage enables the combination of nanomechanics with a wide range of detectors and techniques, such as FIB milling, crystal orientation and compositional analysis, among others.

The PI 89 SEM PicoIndenter provides nanomechanical testing capabilities inside a SEM. It is the first in-situ instrument with two rotation and tilt stage configurations. This allows flexible sample positioning toward the electron column for structure-property correlation studies of complex materials.  For example, imaging, FIB milling, EDS/EBSD measurement, and various other detectors. 

In this application example, an austenitic steel sample is investigated using the combination of PI89 and serial sectioning (FIB) with subsequent EBSD measurement using eFlash FS EBSD detector. The 3D EBSD data are reconstructed and processed with ESPRIT QUBE software. The local and plastic properties of different domains are determined by analyzing the load-displacement curves of several indentation across these domains and the distribution of local average disorientation and geometrically necessary dislocation density.

Who should attend?

  • Researchers from academia and industry, who investigate deformation mechanisms of materials, crystal plasticity and strength of heterogenous materials.
  • Everyone interested in Scanning Electron Microscopy and nano- to micro-mechanical testing.
