The aim of our work is to synthesize molybdenum nitride by a simple, low-temperature route.
Fourier transform infrared spectra of the polymer and its pyrolyzed compounds in KBr pellets were carried out using a Thermo-Nicolet Nexus-870 FT-IR spectrometer.
The pyrolyzed compounds were characterized by FTIR and XRD.
X-ray diffraction curves for the pyrolyzed compounds at 400 oC and 800 oC are shown in Fig. 3 and 4.

The alloys prepared using rapid solidification consisted of SmCo5 matrix phase, MgCu2-type SmCo2 secondary phase, and small traces of Sm2Co7 phase.
The Sm-Co binary equilibrium phase diagram contains five Sm-rich intermetallic compounds: Sm2Co17, SmCo5, Sm2Co7, SmCo3, and SmCo2.
Therefore, replacing Sm2Co7 and SmCo3 phases with SmCo2 in SmCo5 compounds will potentially get high coercivity without the introducing of low anisotropy field phases.

Die-cast AZ91D and rolled AZ31B alloys, which are commercial magnesium alloys,
were used in this study.
Many protective surface treatments of magnesium alloys have been reported.
In this study, the micro-arc oxidation by pulse DC was applied to magnesium alloys (AZ91D, AZ31B) with the aim of improving the corrosion resistance.
Potentiodynamic polarization curve obtained for magnesium alloys in Celine solution.

The combination of e. g. aluminium with steel allows to produce hybrid compounds with wear-resistant functional surfaces and reduced weight.
For this reason, the aim of the Collaborative Research Centre 1153 is to realise new process chains to produce hybrid solid components with load-adjusted properties using semi-finished workpieces joined prior to forming [1].
In [4], the feasibility of the co-extrusion of asymmetric aluminium-titanium compound profiles was shown.
Thus, the maximum tensile strength of the specimens testing the weld seam complies with the tensile strength of the alloy.

This paper aims to study the formability characteristic of Magnesium alloy by considering variable parameters, such as the sheet thickness, forming pressure and forming temperature.
Introduction Magnesium alloys have attracted significant interest to be used in many applications, especially in the aerospace and automotive industries.
Magnesium alloys often exhibit relatively poor formability at room temperature due to the basal or near basal texture usually developed during rolling.
Until now, only limited work has been available about the superplastic behavior of Magnesium alloys.

Properties and Structure Electrodeposition Alloys and Composite Electrochemical Coatings of Nickel-Based
K.V.
Metals (nickel, copper, iron, zinc, tin, silver, gold) or alloys (nickel-boron, nickel-phosphorus, etc.) can be used as a CEC matrix.
A distinctive feature of these electrolytes is the formation of metal coatings due to the reduction of not only metal ions, but also colloids and / or finely dispersed compounds of this metal.
The aim of this study is to study the physical and mechanical properties and structure of nickel-cobalt (Ni-Co) electroplated alloys and nickel-cobalt-nanodiamond (Ni-Co-ND) electroplating alloys obtained from colloid electrolytes.
Thus, the leveling effect on the structure of galvanic deposits of dispersed additives, as well as colloidal compounds of nickel and cobalt, has been determined.

Because of those properties, Mg
alloys have been widely used even for structural components in the automobile, aerospace and
electronics industry to replace some existing materials [1, 2].
Until now, the casting of magnesium alloys is the first processing technique and the use of die cast process is expected to become more important as well.
The present study aim to investigates the behaviour of AZ31 sheet (magnesium alloy with 3% of aluminium and 1% of zinc) in the deep drawing process at elevated temperature.

Further increasing of Y content causes a
formation of binary and ternary nanocrystalline compounds i.e.
In contrast to this the addition of 15 at.% Gd (Gd15 sample) causes a formation of nanocrystalline Fe2B, Fe2Gd and Fe23B6 compounds.
An increase of the Y content leads to the creation of a nanostructure of some binary and ternary chemical compounds.
Further increase of the Y content (13 and 23.1 at.%) leads to formation of binary and ternary nanocrystalline compounds i.e.
