The TiAl-Si alloys appear to form Al Ti and Si oxides.
Introduction Titanium aluminides intermetallic compounds have received great attention during the past decade, since they have the potential, in aircraft and automotive engines, to replace the high density Ni-base superalloys [1-3].
Therefore, a number of studies [5-6] aimed to improve the oxidation resistant of the titaniumaluminde by alloying addition rather than applying a coating.
Due to this reason a large number of silicide plates were observed in alloys having high concentration of silicon.

Therefore, a new technology route which is titanium alloy powders →compaction at room temperature → sintering under dynamic atmosphere of pure argon → vacuum annealing → titanium alloy product will be used to gain the aim of consolidation synergism and improve product properties of hydrogenated titanium alloy powder.

However, the fabrication of components made up of Mg and Al alloys requires bonding techniques suitable for the development of Al/Mg joints.
For Al/Mg an additional issue is the different physicochemical properties of these materials, which usually lead to the formation of brittle Mg–Al intermetallic compounds and to early cracking of the joint.
Table 1: Mechanical properties of the investigated alloys.
As already observed in the literature for homogeneous Al and Mg welded joints, this behavior can be addressed to the formation of brittle intermetallic compounds.

Therefore, it is proposed to consider the cooling of alloys located in the area of primary crystallization of silicon.
In this system, three congruent-melting binary compounds are formed: titanium carbide (TiC) and titanium silicides (TiSi2 and Ti5Si3).
Several compounds are known in these systems: Fe2Si, FeSi, FeSi2.3, TiSi2, Ti5Si3, TiFe2, and TiFe.
In the Si-Fe-C system, there are three compounds that melt congruently: Fe2Si, FeSi, and FeSi2, but all these compounds are in the Fe-Si binary system.

Introduction Precipitation hardenable magnesium-heavy rare earth alloys, containing neodymium and gadolinium, are attractive for aerospace and racing automotive industries because of their high specific strength and good thermal stability.
The strength of this magnesium alloys with RE is achieved essentially via precipitation strengthening.
These alloys precipitate from the solid solution according to the sequence of phases: α-Mg→β"→β' →β.
The aim of the present paper was to determine the effect of heat treatment parameters on the microstructure of Elektron 21 magnesium alloy.

Abstract: This paper aims to present the mechanism of PECVD SiOx coating thin layer technology on biomaterials, such as Ti and its alloys, with reference to the available literature.
Their compounds are non-toxic and non-explosive and hence, no special safety installation is required as in the case of silane.
In Figure 2 it is possible to observe a general sketch mechanism deposition of SiOx on substrate such as Ti or Ti alloys, in case that the plasma chamber is alimented with organosilicon compounds.
Titanium alloys primarily stand out due to two properties: high specific strength and excellent corrosion resistance.

The aim of this paper to show the dynamic properties of these hybrid joints.
The different aluminium alloys have different properties, so different technological parameter combinations were used.
The 6082-T6 base material is one of the most widely used aluminium alloys.
