We examine experimental and theoretical results on the cold-work (Snoek-Köster) peak in bcc Fe due to H using density functional theory (DFT). We reaffirm that Seeger’s interpretation of the H cold-work peak (Hcwp), involving motion of H with kink

We have used density functional theory (DFT) to determine binding energies (BE’s) of carbon-vacancy (C-v) point-defect complexes of probable importance to C-based anelastic relaxation processes in fcc iron alloys. Calculations are presented for thr

We previously performed a series of density functional theory calculations to investigate the interaction between single H atoms and point defects in body-centered cubic (bcc) Fe (Counts W, Wolverton C, Gibala R. Acta Mater 2010;58:4730). Here, we ex

The dependence of the carbon Snoek peak height on preferred orientation determined from inverse pole figures has been examined in two aluminum-killed and two silicon-treated steels. Texture variations were produced by cold rolling and annealing and b

Our research and results from the literature all consistently suggest a binding energy of nearest-neighbor carbon-vacancy (C-V) pairs of the order 35 to 40 kJ/mole in austenitic alloys. Results examined include point-defect anelasticity, self-diffusi

Several research results suggest the binding energy of carbon–vacancy (C–V) complexes is of the order 35–55 kJ/mole in face-centered cubic (fcc) iron-base alloys. In addition to point-defect anelasticity, we examine data on self-diffusion of Fe

A series of carbon coatings was deposited on a 1040 SiC monofilament using chemical vapor deposition, and failure of the fiber-matrix interfacial region under transverse tension was studied. Deposition substrate temperatures were approximately 920, 1

We have examined the effects of a fine dispersion of precipitates in the matrix phase of two multiphase NiAl-based alloys on strength and toughness. The first system is a directionally solidified Ni–30Fe–23Al alloy composed of a B2 matrix reinfor

We have studied the mechanical behavior of model NiAl-based eutectic composites to gain insight on micromechanisms of plasticity in multiphase intermetallics. We show that in composites where the NiAl matrix and the reinforcing ductile second phase c

The effect of a ductile γ′-Ni3Al phase on the room-temperature ductility, temperature-dependent yield strength, and creep resistance of β-NiAl was investigated. Room-temperature tensile ductility of up to 9 pct was observed in directionally solid
