Thus, the aim of this study is to investigate tensile properties of Sn-5Sb and Sn-3.5Ag-0.5Cu-0.07Ni-0.01Ge alloys using miniature size specimens which have microstructures similar to real solder joints [17-19].
For elongation, a similar tendency was observed in both alloys.
In Sn-5Sb, as shown in Fig. 1, the microstructure consists of fine β-Sn phases and fine SbSn compounds.

The investment casting process is one of the ideal forming methods for producing the near-net-shape structural parts for the aluminum alloys and nickel-based super alloys.
However, because of the high reactivity between the high temperature melts of magnesium alloys and the ceramic oxides, the investment casting process of magnesium alloys has been restricted.
However, as investment mold is usually firsintered at temperature 850~1000℃, those fluorine-containing compounds that are unstable below this temperature will be lost whereas those that are stable at or above this temperature not break down at magnesium casting temperature.

Nonoxide High-melting Point Compounds as Materials for Extreme Conditions S.S.
Introduction Nonoxide high-melting compounds, i.e. metal-like borides, carbides, nitrides, and silicides of the d- and f-metals, as well as covalent compounds like SiC, В4С, etc., are finding ever wider applications in development of the promising ceramic materials.

Brazing with amorphous alloys require high heating and high cooling speeds, in order to avoid the precipitation of intermetallic compounds and formation of a single phase such as solid solutions.

The XRD results revealed TiB-TiB2 biphasic B-Ti compounds layer formed on the surface of TC4 after RE-boriding.
Introduction Ti-6Al-4V (TC4) is the most widely used titanium alloy in the aerospace industry, with the occupation ratio of more than 50% of the total titanium alloys [1-2].
As Al atoms can not dissolve in the boride compounds, so the content of Al on the boride layer is only 0.035% (in mass percent concentration).

The study of phenomena occurring during the crystallization of the ZnAl22Cu3Si alloy with ATD methods have shown that silicon does not form compounds and solid solutions with Zn and Al.
Silicon does not form compounds and solid solutions with Zn and Al (as in silumins).
The aim of the examinations was to determine the influence of REE addition (rare earth elements) on the distribution of silicon precipitates in the ZnAl22Cu3Si cast alloy.

Moreover, Al alloys have relative good workability and excellent corrosion resistance so that the lightweighting of the body using Al alloys has attracted attention.
However, since the manufacturing cost of Al alloys is relatively high and the strength and rigidity of them are lower than those of steel, it is difficult to constitute the whole body with Al alloys [1].
The brittle intermetallic compounds layer formed at the joint interface also becomes the problem in the dissimilar resistance spot welding [9].
The thickness of the intermetallic compounds (IMCs) layer formed at the joint interface was also investigated with a OM.
It was confirmed that the reaction layer consists of Fe-Al intermetallic compounds (IMCs) such as FeAl, FeAl2, Fe2Al5 and FeAl3.

These alloys have been developed with non-toxic elements, such as Nb and Mo, aiming to combine high strength with low Young’s modulus, in order to avoid stress shielding and also influence the formation of a protective oxide, necessary to the excellent corrosion resistance of these materials. [4-9].
It can be observed that the alloys presented different behaviours, however both alloys exhibited spontaneous passivation.
