A verification of immiscibility in InGaAsP quaternary alloys

Journal of Crystal Growth, 1988
Abstract Immiscibility in the InGaAsP quaternary alloys is studied by using liquid phase epitaxy. Growths are performed on GaP substrates instead of GaAs substrates for several melt compositions, which produce lattice matched alloys with GaAs when the growths are done on GaAs substrates.

Synthesis of Immiscible Alloys by the Mixalloying Process

Journal of Engineering for Industry, 1989
Dispersed-phase microstructures of the immiscible Pb-Zn, Pb-Zn-Sn and Pb-Al alloys were produced by the Mixalloying Process [1]. The particle size was found to follow the log-normal statistical distribution and the mean particle diameter correlated well with the –3/5th power of the Weber number. Furthermore, computational simulation studies showed that

Surface-Confined Alloy Formation in Immiscible Systems

Physical Review Letters, 1995
Elements which are immiscible in the bulk have been found to form stable two-dimensional mixtures at the free surface. Here we show that such surface-confined mixing is expected quite generally in systems which are dominated by the atomic size mismatch.

Segregation and immiscibility in liquid binary alloys

Reports on Progress in Physics, 1997
An overview of the thermophysical properties of segregating and demixing liquid binary alloys is presented encompassing the simple approaches that are commonly used by physicists, chemists and metallurgists in general. The various experimental and theoretical information available for such systems are put together to establish a respectable ...

IMPINGEMENT CASTING PROCESS OF IMMISCIBLE ALLOYS

Advanced Manufacturing Processes, 1987
ABSTRACT Experimental work on impingement casting process of Pb-Zn, Pb-Zn-Sn and Al-Pb systems was carried out. Rapid mixing of immiscible liquid metals was achieved in an arrow-shaped mixing chamber due to vigorous turbulence. The particle size distribution in the castings fitted lognormal curve well.

Strain Stabilized Alloying of Immiscible Metals in Thin Films

Physical Review Letters, 1995
We report on the structure and composition of codeposited thin Ag and Cu films on a Ru(0001) substrate. All three metals are immiscible in their bulk forms, however, monolayer films of Ag and Cu are observed to alloy on Ru(0001). In the dilute Cu case, preferential formation of the alloy is found.

Formation of Immiscible Alloy Powders with Egg-Type Microstructure

Science, 2002
The egg-type core microstructure where one alloy encases another has previously been obtained during experiments in space. Working with copper-iron base alloys prepared by conventional gas atomization, we were able to obtain this microstructure under gravity conditions.

Immiscible alloys under microgravity conditions

Advances in Space Research, 1988
Abstract The decomposition of immiscible metallic alloys into a dispersion of liquid droplets in a liquid matrix and its spatial development is considered with reference to selected experiments performed in experiment facilities under microgravity conditions. The analysis and discussion of these experiments reveal, that research in space laboratories

Liquid immiscibility in ternary metallic alloys

Materials Science and Technology, 1991
AbstractTwo models have been proposed which can be used to predict the occurrence of liquid immiscibility in ternary metallic alloys. One model, derived from an earlier proposal by Axon for predicting liquid immiscibility in binary alloys, was based on differences in the atomic sizes and melting points of the metals.

Alloys created between immiscible elements

Progress in Materials Science, 2005
Abstract The development and understanding of alloys is one of the most important themes of physical metallurgy. Over the past four decades, the progress in modern processing techniques has enabled researchers to artificially create an increasing number of new alloys in systems that are immiscible in thermodynamic equilibrium.
