Transport properties of dilute alloys
The review introduces the reader to a theoretical method describing the transport properties of dilute alloys on an ab initio basis. The calculations start from density or spin density functional theory using a Green function formalism to investigate the underlying electronic structure of the ideal and perturbed system on equal footing. The residual resistivity is calculated solving the quasicl...

متن کاملPrecipitation hardening in dilute Al–Zr alloys
The aim of this study was to investigate the effect of solute content (hipoperitectic Al–0.22 wt.%Zr and hiperperitectic Al–0.32 wt.%Zr) on the precipitation hardening and microstructural evolution of dilute Al–Zr alloys isothermally aged. The materials were conventionally cast in a muffle furnace, solidified in a water-cooled Cu mold and subsequently heat-treated at the temperature of 650 K (3...
متن کاملNUCLEAR MAGNETIC RESONANCE iN DILUTE ALLOYS
The experimental results concerning the electric field gradient and the local magnetic field around substitutional impurities in copper-based dilute alloys have been summarized. Comparing the experimental data with theoretical models we have come to the conclusion that only the first-order quadrupole wipe-out number characteristic of the asymptotic charge density oscillation around the impuriti...
متن کاملElectronic Structure of Dilute Bismide Alloys
The dilute bismide semiconductor GaAs1-xBix represents an interesting counterpart of the dilute nitride alloy GaAs1-xNx. Both exhibit giant bandgap bowing phenomena but with oppositely directed effects on the valence and conduction bands respectively. The optical properties of the dilute bismide alloy will be contrasted with those of the dilute nitride and the similarities and distinctions betw...
