Ab initio calculations of the lattice parameter and elastic stiffness coefficients of bcc Fe with solutes
(2016-04-20)
Density functional theory calculates the effects of substitutional Al, B, Cu, Mn, Si solutes, and octahedral interstitial C and N solutes on the lattice parameter and elastic stiffness coefficients of bcc Fe at 0 K. We ...
Geometries of edge and mixed dislocations in bcc Fe from first principles calculations
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. ...
Impact of solutes on the lattice parameters and elastic stiffness coefficients of hcp Fe from first-principles calculations
(2018-12-16)
The hexagonal close-packed (hcp) $\epsilon$-martensite phase in steels nucleates from the austenite parent phase during plastic straining and can be stabilized by solute additions. We compute the lattice parameters and ...
