Alloys based on nickel aluminides are used for doping and modifying non-ferrous alloys [2, 3].
Alloys based on intermetallic compounds are known to be used as materials for producing composite coatings with high heat and wear resistance [8].
The aim of the work was to obtain composite alloys doped with zirconium, tungsten, its borides and a carbides from oxides, including mineral concentrates by means of liquid-phase method SHS.
The use of a mineral concentrate containing Zr in producing alloys based on the Al - Ni system leads to grinding of the alloy microstructure and the formation of the intermetallic compounds containing zirconium.

Among all the non-ferrous metal alloys, Zamak is the most used industrially in squeeze casting (injection), due to its physical and mechanical properties.
The substrate used in this study was Zamak 5, that is one of the alloys most used for casting by injection.

This paper discusses the preparation of partially amorphous Al90Fe5Cr5 and Al90Fe7Cr3
powder alloys by mechanical milling and their subsequent consolidation by hot milling.
The high hardness values of about 417HV of the intermetallic compounds formed during the rolling process presented the main obstacle to obtaining totally homogenous and consolidated samples.
Introduction Many different microstructural combinations of Al-based alloys are now under investigation aiming to optimize the already good values of mechanical strength observed in amorphous nanocrystalline composites [1-3].
The samples treated at 350°C presented not only Al peaks but also peaks corresponding to the intermetallic compounds Al3Fe and Al5Cr, indicating that these compounds probably already existed in the milled sample, although they were not observed in the XRD patterns of that condition.

The
corrosion rate of magnesium alloys can decrease from 1.10 mg/(cm2.d) to 0.17 mg/(cm2.d) by 84%
with the use of flux containing 5% LaCl3.
By far, there is few research reports about RE contained compound added to Mg alloy melt.
The aim is to explore a new way to improve the Mg alloy properties.

Giant magnetic entropy change around room temperature was obtained in materials with the first-order magnetic phase transition, such as the Gd-based alloys Gd5(SixGe1-x)4 [3], the Fe-based LaFe13−x(Al,Si)x [4] and Fe-Rh [5], the Mn-based Ni-Mn-Ga alloys [6], as well as MnAs [7-9].
The single-phase state of the alloys was established from x-ray diffraction patterns of powder samples at room temperature.
With the aim to investigate MCE in wide field range the magnetization isotherms for the investigated compounds have been obtained at some selected temperatures around of phase transition in magnetic field up to 140 kOe.

It is found that the intermetallic compounds formed on the grain boundaries are less in Zr modified 5182 than 5182 alloys for the as-cast structure.
From the results of observations in fig.1(a), the grain size is about 250µm, a little dendritic structure and intermetallic compounds on the grain boundaries can be seen in the 5182 alloys.
Since the dendritic structure and intermetallic compounds cann’t be seen easily in Fig.1(b), the change during homogenizing heat treatment is not evident in Zr modified 5182 alloys(in fig.3(b)).
Conclusions (1).In the 5182 as-cast alloys, There are a little dendritic structure and intermetallic compounds distributed on the grain boundaries.
Adding of 0.11wt.% Zr did not reduce the grain size of the alloys, but the dendritic structure within the grains disappear and intermetallic compounds on the grain boundaries decrease

SME behavior changes in the homogeneity range of HfIr compound are discussed
Introduction
During the last two decades, the new class of functional materials appeared – high temperature shape memory alloys (HTSMA) [1, 2].
So, the aim of the present paper was to study martensitic transformation and shape memory effect in the homogeneity range of HfIr intermetallic compound.
The results of such tests for HfIr50.3 and HfIr51.7 intermetallic compounds are shown in Fig. 3.
