Many authors reported that this technology offers different combined advantages such as degassing, grain refinement and eutectic Si and Fe-rich compounds modification in aluminum casting alloys [8-11].
This latter phenomenon results in the formation of intermetallic compounds, mainly Fe2Al5 (η) and, in a minor extent, FeAl3 (θ) phases [19].
However, dissolution occurs as well via the formation of NbAl3 intermetallic compounds [20-21].

SPD alloys, along with the NС formation, can lead to the formation of metastable states, for example, supersaturated solid solutions and metastable intermetallic compounds that can lead to disruption of long-range order up to complete disordering.
Figure 3 (а, b) shows electron diffraction pattern alloy D16 after one (Fig.3, а) and ten (Fig.3, b) revolutions of HPT with point reflections from intermetallic compounds.
Reflexes of intermetallic compounds Q(CuAl2), Cu9Al4 on electron diffraction patterns (Fig. 3, а, b) were weak that indicated a small amount of these particles.

Introduction Many studies conducted to analyze the structural and morphological changes of organic compounds in ambient pressure have been done.
Nevertheless, to get a better understanding of the nucleation process and especially the determination of the influence of hydrogen on the synthesis process, the study of the carbonization-graphitization of organic compounds has been a subject of recent research.
This treatment aimed to produce anthracene carbonization.

Structure and Properties of Diamond-Like Carbon Coatings Deposited on Non-Ferrous Alloys Substrate T.
The aim of this innovative work was to obtain best possible hybrid coatings, consisting of – a gradient transition layer, with a continuous change of one or more components reaching from the substrate to the surface top – as well as an outer coating using the PACVD process on the surface of the cast magnesium and aluminium alloys, to increase of low stiffness of the substrate material.
Experimental procedure The investigations have been carried out on test pieces of magnesium and aluminium alloys (Table 1).
As a result of the performed X-ray microanalysis using the qualitative energy spectrometer EDS it was confirmed the presence of major alloying elements Al, Si, Cu, Ti, C, as compounds of the investigated alloys (in this case cast aluminium) as well of the coatings (Fig. 7).

The incorporation of multi-principal elements in alloys has always not been considered because of the anticipated formation of complex microstructures composed of multiple-phase intermetallic compounds or ordered phases.
In this paper, we aimed to prepare HEAs with high melting point as well as excellent ductility.

Therefore, silane based coatings may be a good option for improving the corrosion resistance of the magnesium alloys.
The aim of this study is, therefore, to develop a phosphonato silane based coating on Mg-6Zn-Ca alloy using sol-gel technique to improve corrosion resistance of the alloy.
Metals and alloys generally require a surface pre-treatment for effective adherence of silanes.
Therefore, the change in pH in the bare and the coated alloys was monitored throughout the corrosion tests.

In particular, the corrosion performance of magnesium alloys represents one of the most prominent problems.
Some of the inter-metallic compounds can be formed at interface between dissimilar metals after heat treatments.
The fracture of the Al/TRC Mg/Al composites annealed at or above 300 °C was initiated from the interface influenced by brittle behavior of inter-metallic compounds, followed by fracture of TRC AZ31 alloy.
