Dynamics of commensurate chromium alloys
Physical Review B, 1994The dynamics of commensurate chromium alloys are produced by the fluctuations of a spin-density wave consisting of bound electron-hole pairs. For a commensurate alloy at any temperature, we find a transverse spin-wave (SW) mode with frequency \ensuremath{\omega}=cq and a longitudinal amplitude mode with dispersion \ensuremath{\omega}=2\ensuremath{\surd}

Recasting a nickel-chromium alloy
The Journal of Prosthetic Dentistry, 1986lhe escalating cost of gold has contributed to the widespread use of base metal alloys for fabrication of removable partial denture frameworks. The popularity of base metal alloys is further enhanced by their resistance to corrosion, reduced weight, and generally more favorable physical properties than those of gold.’ As an economy measure, excess gold

Cast chromium alloy surgical splints
The Journal of Prosthetic Dentistry, 1976A cast chromium alloy surgical splint can be fabricated in less than 6 hours. This splint has the advantages of being well fitted, smooth, rigid, and less bulky than prefabricated splints. Other metals can be utilized in a similar manner to fabricate cast surgical splints.

The creation of superior heat-resistant materials is one part of the classical problem of efficiently converting thermal energy into ordered kinetic energy and will remain an important part so long as the Second Law of Thermodynamics is a guiding principle in the improvement of heat engines.

Dislocation structure in chromium, chromium-rhenium, and chromium-iron alloys
Journal of the Less Common Metals, 1966Abstract Electron-transmission microscopy experiments were performed on chromium, chromium-rhenium, and chromium-iron alloys to investigate the effect of alloying on dislocation multiplication and configuration. It was found that the increase of dislocation density with strain was largely independent of composition, but that large alloying additions ...

This paper presents data on the linear thermal expansion of various heat resisting alloys (nickel-chromium, iron-chromium and nickel-chromium-iron alloys) manufactured in the United States. These data will be useful to physicists, engineers, metallurgists and others in the use of these alloys, for example in the design of equipment for modern processes.

The diagram in Fig. 108 is due to [1]. It is based on the work of [2]. This diagram was compiled from data obtained over the whole composition range by metallographic, X-ray diffraction and electron microprobe investigations. The two intermediate phases, the E close-packed hexagonal (hcp) phase and the β Cr3Si (A15) phase have composition ranges of ~20

Superconductivity of Chromium Alloys
Physical Review, 1962The superconducting properties of Cr-Ru, Cr-Rh, and Cr-Ir alloys have been investigated and the transition temperatures have been determined as a function of composition and of valence-electron concentration.The Cr-Ru system contains three superconducting phases all of which have a homogeneity range. A hexagonal close-packed alloy containing 50 at.% Cr

Abstract Chromium alloys yield alloy coatings with properties that range from completely satisfactory to marginally acceptable, depending on the end use. This article provides a detailed description of plating solutions and deposition conditions and rates of chromium-iron, chromium-nickel, and chromium-iron-nickel alloys.
