The aim of this work was to describe the dependence of microstructure of NiTi shape memory alloy on the conditions of powder metallurgy processing route.
Introduction The alloys having the shape memory effect can be found in several alloy systems, e.g.
In this process, powders of metals or alloys are blended and compressed.
To use this ability, the alloys with higher nickel content have to be used [3].

The amorphous alloys are difficult to weld by conventional melting processes, even in the presence of inert gas.
Introduction Amorphous metal alloys are relatively recent materials, produced since 1960 as micrometer-thick ribbons by rapid cooling on a rotating cylinder.
The most common method for obtaining amorphous alloys in ribbon form with larger widths is the Planar Flow Casting method.
The addition of Si and B aimed to increase the glass forming ability of the alloy and improve the thermal stability of the amorphous phase [5].

In this scenario, aluminium alloys are an interesting alternative to conventional ferrous alloys, since they can combine low density and good mechanical properties at the same time.
One of the solutions to overcome this problem is to take advantage from the capability of heat treatable aluminium alloys, in particular the Al-Mg-Si alloys, in hardening/softening if treated in different conditions.
The aim of the present work is to correlate the effect of the aging phenomenon on the mechanical properties of the AC170PX alloy to a specific temperature gradient profile on the specimen.

Among diversity of the known nanosized objects the metal nanopowders and their compounds are the most promising in the said area of study [1–3].
The area of application of copper nanopowders (Cu NP) is considerably wide: metallurgy (additive of Cu NP affects the strength and elasticity of alloys), powder metallurgy (the use of Cu NP enables production of new composite materials and alloys at lower temperatures), in electronic industry the said additives affects the conductivity and optical properties of coatings and layers, in chemical industry Cu NP were proved to be effective active components of catalysts for petrochemical synthesis and metal-plating additives for motor and transmission oils [4,5], in printed electronics Cu NP can be used as materials that has low melting temperature and high conductivity and are more economically reasonable in comparison with currently used gold and silver [6].
This work is aimed at the study of influence of Cu NP production conditions, namely the amount of energy introduced into the wire, on their properties.
The aim of the work needed to establish an experimental relation between the energy introduced into the wire e and the number average size of particles a.
