Effect of solutes on the lattice parameters and elastic stiffness coefficients of body-centered tetragonal Fe

Fellinger, Michael R.; Hector, Louis G. Jr.; Trinkle, Dallas R. (2018-03-03)

We compute changes in the lattice parameters and elastic stiffness coefficients Cij of body-centered tetragonal (bct) Fe due to Al, B, C, Cu, Mn, Si, and N solutes. Solute strain misfit tensors determine changes in the ...
Geometries of edge and mixed dislocations in bcc Fe from first principles calculations

Fellinger, Michael R.; Tan, Anne Marie Z.; Hector Jr., Louis G.; Trinkle, Dallas R.

We use density functional theory (DFT) to compute the core structures of a_0[100](010) edge, a_0[100](011) edge, a_0/2[-1-11](1-10) edge, and a_0/2[111](1-10) 71 degree mixed dislocations in body-centered cubic (bcc) Fe. ...
