Alloys properties

Comprehensive details of alloy properties and characteristics are provided in the publications of the major aluminium companies and independent organisations. ... 

An alloy is said to be of Type II if neither the AC nor the BC component has the structure a as its stable crystal form at the temperature range T]. Instead, another phase (P) is stable at T, whereas the a-phase does exist in the phase diagram of the constituents at some different temperature range. It then appears that the alloy environment stabilizes the high-temperature phase of the constituent binary systems. Type II alloys exhibit a a P phase transition at some critical composition Xc, which generally depends on the preparation conditions and temperature. Correspondingly, the alloy properties (e.g., lattice constant, band gaps) often show a derivative discontinuity at Xc.

Thermochemistry of cluster compounds. In this short summary of cluster structures and their bonding, a few remarks on their thermochemical behaviour are given, in view of a possible relationship with the intermetallic alloy properties. To this end we remember that for molecular compounds, as for several organic compounds, concepts such as bond energies and their relation to atomization energies and thermodynamic formation functions play an important role in the description of these compounds and their properties. A classical example is given by some binary hydrocarbon compounds. 

In conclusion, bimetallic AuPt nanoparticles prepared by two-phase synthesis, assembly on carbon, and thermal calcination were shown to display alloy properties.

The electrodeposition of Zn-Sn alloys was studied using the EQCM method [440]. The influence of electrolyte composition on the Zn-Sn alloys properties was investigated and discussed [440-442].

Next, the current status of the theoretical understanding of alloy phases is reviewed. The techniques available for first-principles calculations for alloys (and alloy phase equilibria) up to the 1990s are listed and reviewed by de Fontaine. Current thinking is reviewed by Pettifor who is also a major contributor to the understanding of alloy properties by fundamental computations. 

Pettifor showed how density functional theory (DFT, see above) may strengthen the CALPHAD conclusions for complex alloy systems by providing information on compositionally nearby metastable alloy phases that may affect alloy properties.

Metals can be mixed with one or more other elements, usually other metals, to make an alloy. The mixture of elements in an alloy gives the alloy properties that are different from the properties of the individual elements. Often these properties eliminate some disadvantages of the pure metal. A common alloy is brass, a mixture of copper and zinc, which is harder than copper and more resistant to corrosion. Brass has a wide range of uses, from inexpensive jewelry to plumbing hardware. Another alloy made from copper is sterling silver. A small amount of copper is mixed with silver to produce sterling silver, which is used for both jewelry and flatware.
