This is also the reason why most exiting Mg-Al alloys (such as AZ, AM magnesium alloys) has a content of Al less than 10wt.%.
The possibility of the formation of metallic compounds is relative to the elements’ electronegativity difference.
The more the electronegativity difference, the easier the formation of the compounds[9].

Thus, Sn–Ag–Cu alloys have been proposed by the Japanese (Sn–3.0 wt.
However, because of the rigidity of high-Ag-content in Sn–Ag–Cu alloys compared to Sn–Pb solder alloys, more failures may occur in drop- and high-impact situations in portable electronic devices that contain these solder joints.
Apart from that, the high Ag content in Sn–Ag–Cu alloys results in a relatively high cost for these materials.

The aim of the present works, which is the first step of a more complex research, is to investigate
the tarnish copper compounds developed on bronze alloys exposed to sulfur dioxide and submitted
to cycling wet and dry tests at 200 ppm, 40°C and 100% RH.
Patinas with comparable colorimetric measurements are probably formed by the same copper compounds.
The localized tin rich areas are made of oxide and sulphide tin compounds (Ottemannite and Cassiterite).
Surfaces with same color parameters probably are made of the same compounds.

The aim of the IMRC is provide an
interactive forum to discuss and exchange ideas about the advances in synthesis, characterization,
properties, processing, applications, basic research trends, corrosion prevention, and more, all
related to the area of materials science and engineering.
The Symposium 5C "Structural and Chemical Characterization of Metals, Alloys and Compounds" promotes the contact among scientists and research groups for the creation and collaboration of national and international research networks.
The structural, mechanical and chemical characterization of different materials such as metals, alloys, ceramics, catalysts, steels, composites, welding, superalloys, quasicrystals, intermetallic compounds, and nanomaterials are included.
Finally, but not least, we would like to thank all the authors for their valuable contributions to the journal.

The paper deals with the specific topics on directional solidification of following advanced
materials: column and single crystal superalloys under high thermal gradient, Ni-Cu alloys under
deep supercooling of the melt, intermetallic compounds with selected preferential crystal
orientation, superalloys with container less electromagnetic confinement, high Tc superconducting
oxides, high temperature structural ceramics, continuous cast single crystal copper and
copper-based composites.
A variety of structural and functional materials, such as single crystal superalloys, in-situ eutectic composites, high temperature intermatallic compounds, high-Tc superconductors, are prepared mainly via directional solidification.
Its principle is based on eddy current within the alloys and electromagnetic pressure on the surface of specimen from induction coil around the specimen.
It was found that the easy axis of magnetization of Nd-Fe-B alloys is perpendicular to its preferred growth direction even through the crystal growth of this alloy can be directionally controlled in solidification.

Studies conducted to determine the influence of the laser beam on SMA's have reported an increased susceptibility to the formation of intermetallic compounds, different grain sizes, the presence of residual stresses, or affinity for atmospheric gases. [8, 10-16].
In this case, the low Ni content may be due to preferential volatilization of Ni, because the fusion zone is subjected to higher temperatures and not to the presence of intermetallic compounds, as reported in other cases. [23, 26-29].
