Webinar: Using Diffraction-contrast Electron Microscopy to Elucidate Dislocation Pathways in Refractory Multi-principal Element Alloys

Refractory multi-principal element alloys (MPEAs) are promising candidates for structural applications demanding mechanical robustness at temperatures exceeding the capacity of state-of-the-art superalloys. While excellent high temperature strength has been demonstrated in many refractory MPEAs, a fundamental understanding of the nature of dislocation pathways in the BCC versions of these chemically complex alloys and their ability to enable macroscopic ductility is still in its infancy.

 In this webinar, attendees will learn:

  • How in situ scanning transmission electron microscopy in a scanning electron microscope can study the dynamics of dislocation slip pathways in these chemically complex materials
  • How diffraction contrast transmission electron microscopy can quantify the character and slip planes of dislocations generated in these materials
  • How synergies between electron microscopy and simulation can be combined to uncover the origins of unusual slip pathways
