Can Symmetric Tilt Grain Boundaries Represent Polycrystals?
Malik Wagih, Christopher A. Schuh
Grain boundaries control a wide variety of bulk properties in polycrystalline materials, so simulation methods like density functional theory are routinely used to study their stru…
The Spectrum of Interstitial Solute Energies in Polycrystals
Malik Wagih, Christopher A. Schuh
A computational method is presented to measure the spectrum of segregation energies for an interstitial solute at grain boundaries (GBs) in a polycrystal. For the Pd-H system, that…
Crystal orientation and detector distance effects on resolving pseudosymmetry by electron backscatter diffraction
Edward L. Pang, Christopher A. Schuh
Accurately indexing pseudosymmetric materials has long proven challenging for electron backscatter diffraction. The recent emergence of intensity-based indexing approaches promises…
Resolving pseudosymmetry in tetragonal ZrO2 using EBSD with a modified dictionary indexing approach
Edward L. Pang, Peter M. Larsen, Christopher A. Schuh
Resolving pseudosymmetry has long presented a challenge for electron backscatter diffraction (EBSD) and has been notoriously challenging in the case of tetragonal ZrO2 in particula…
Global optimization for accurate determination of EBSD pattern centers
Edward L. Pang, Peter M. Larsen, Christopher A. Schuh
Accurate pattern center determination has long been a challenge for the electron backscatter diffraction (EBSD) community and is becoming critically accuracy-limiting for more rece…
Supersonic Impact of Metallic Micro-particles
Mostafa Hassani-Gangaraj, David Veysset, Keith A. Nelson +1
Understanding material behavior under high velocity impact is the key to addressing a variety of fundamental questions in areas ranging from asteroid strikes and geological crateri…
A survey of ab-initio calculations shows that segregation-induced grain boundary embrittlement is predicted by bond-breaking arguments
Michael A. Gibson, Christopher A Schuh
The segregation of solute atoms to grain boundaries can have a large influence on the mechanical behavior of polycrystals, particularly in metallic alloys. An overview of 400 calcu…
Segregation-induced changes in grain boundary cohesion and embrittlement in binary alloys
Michael A. Gibson, Christopher A. Schuh
Grain boundary embrittlement occurs when a solute enriches at a grain boundary and lowers its cohesive energy. While grain boundary enrichment is often attributed to equilibrium se…
