Structure and mechanical properties of Cu-X (X = Nb,Cr,Ni) nanolayered composites
Sputtered Cu/Cr and Cu/Nb multilayers have polycrystalline microstructures with nanometer scale grain sizes, while Cu/Ni multilayers evaporated on single crystal Cu or NaCl were single crystalline.Expand

Transient oxidation of Single-Crystal β-NiAl
The transient oxidation of β-NiAl in air at 800 °C and 1100 °C has been studied using electron microscopy. The oxide scale consists predominatly of metastable Al2O3 phases. θ-Al2O3 is the major oxideExpand

Three-stage hardening in tantalum single crystals.
Abstract Three-stage hardening has been found to occur in tantalum single crystals deformed in tension over a limited range of orientations, temperatures and strain-rates. The orientation range isExpand

Enhanced hardening in Cu/330 stainless steel multilayers by nanoscale twinning
Abstract Metallic multilayered composites synthesized by sputter deposition exhibit very high hardness as the bilayer period approaches a few nanometers. In the present investigation onExpand

Crystal growth and low coercive field 180° domain switching characteristics of stoichiometric LiTaO3
We grew LiTaO3 single crystals with a composition close to stoichiometry by using a double crucible Czochralski method. The switching field required for 180° ferroelectric domain reversal and theExpand
