Because Ni-coated Al powders are not self-fluxing alloys and don’t contain the alloy element lowing the melt point or forming slag, the laser cladding performance of the single Ni-coated Al powders is not ideal.
In addition, a small amount of other complex metal compounds may form or precipitate in reaction and cause second phase strengthening or precipitation strengthening effect.

In most cases these technological processes are accompanied by adding refractory compounds to a liquid melt in order to improve physical and mechanical properties of the coatings under formation [1-3].
The main advantages of non-vacuum electron beam cladding are a possibility to add refractory alloying components able to form high-strength compounds during solidification of a surface layer, a high heating velocity, a significant thickness of a cladded layer (up to 5 mm), the absence of cladded metal sputtering, and a high efficiency coefficient of equipment [5-10].
High-alloyed multicomponent self-fluxing Ni-based alloys consisting of Ni, Cr, Fe, Si and B are widely used for obtaining corrosion and wear resistant coating.
The aim of this investigation was to find appropriate technological solutions providing the formation of high-alloyed surface layers using the method of Ni-Cr-Fe-Si-B powder mixture cladding by an electron beam injected into the air atmosphere.

Introduction Shape memory alloys (SMAs) are a class of material that undergoes a reversible shape change after a plastic deformation.
Cu-based shape memory alloys have the advantage of large thermal and electrical conductivities and the system Cu-Al-Ni alloys are quite attractive due to better stabilisation against aging phenomena [2].

However, precipitation hardened Al-Zn-Mg alloys are susceptible to stress corrosion cracking (SCC).
The aim was to distinguish the effects due to hydrogen and the ones due to corrosion phenomena.

Quantitative elemental analysis of these layers showed that Ti3Al, TiAl, and TiAl2 compounds, as well as Ti(Al) solid solution could be formed in these zones.
· At the interface between Ti and TiAl3 thin intermediate layers that may consist of such intermetallic compounds as TiAl2, TiAl, and Ti3Al, as well as of a solid solution of Al in the Ti matrix were formed

The quaternary Ni-Cu-Fe-P alloys provide the possibility of amorphization and some of them may have supercooled liquid region [4].
Furthermore, it is essential to study the thermal stability of such alloys in order to enable the technological tests of consolidation.
Therefore, the aim of the work is to show the change of the microstructure occurring during the heating at the early stages of the crystallization process in the Ni64Cu9Fe8P19 alloy.
However it is not a rule for every alloy, because there are reports on the amorphous alloys with the positive TRC [7].
