Microalloying of MoSi2 to form Mo(1−x)MexSi2 (Me = Nb or V) was investigated by the self-propagating high-temperature synthesis method. With alloying element contents up to 5 at.%, a homogeneous C11b solid solution was obtained. For higher contents of alloying elements, the product contained both the C11b and the hexagonal C40 phases. The relative amount of the C40 phase increases with an increase in the content of alloying metals in the starting mixture. The alloying element content in the hexagonal C40 Mo(1−x)MexSi2 phase was nearly constant at a level of about 12 at.% for all starting compositions. In contrast, the content of the alloying elements in the tetragonal phase is considerably lower (around 4 at.%) and increases slightly as the Me content in the starting mixture is increased.

The results of tribological characteristics of alumomatric composite material Al — 5 % Cu — 2 % Mn — 10 % TiC obtained by the self-propagating high-temperature synthesis method are presented. It is shown that in comparison with technical aluminum and matrix alloy, signifi cantly lower indicators of the coeffi cient of friction, wear and heating temperature characterize composite material, reinforced with nano- and ultrafi ne particles of titanium carbide.

<p>Microstructure and properties of Cu<sub>1-x</sub>Zn<sub>1-y</sub>Al<sub>1-z</sub> ranging through (0.29 &lt;X&lt; 0.30; 0.74 &lt;Y&lt; 0.75; and 0.83 &lt;Z&lt; 0.96) alloys obtained by the Self- propagating High-temperature Synthesis (SHS) were examined. The microstructural and mechanical properties were examined, respectively by X-ray diffraction, tensile tests and Brinell hardness. The obtained results showed that the modification of composition lead to the formation of new phases. Therefore, this microstructure affects strongly the mechanical properties of the selected samples. In this study, we will also highlight the SHS technology and prove that it can alternate the conventional methods regarding the development of a Shape Memory Alloys (SMAs).</p><p> </p>

Bulk Parameters

Due to the convective and radiant heat losses, there exists a maximal converted length of a dense pellet synthesized by the self-propagating high-temperature synthesis (SHS) method. In this paper, we numerically investigate the possibility to increase that maximal converted length by cascading two reactant pellets in series, where an interface is naturally and artificially introduced. First, the impacts of both the bulk and interfacial parameters on the SHS process are estimated. The maximal converted length for a single pellet is computed. Next, by varying the interfacial parameters, it is found that more than 10% of extra converted length is obtained by the proposed cascade arrangement. Effects of the bulk parameters on the same purpose are also addressed.

Abstract The ZnS:Mn, Mg powder is fabricated by self-propagating high-temperature synthesis with the simultaneous introduction of Mn and Mg impurities. It is found that the simultaneous introduction of Mn and Mg impurities leads to the nonuniform distribution of manganese forming regions with a lower and higher Mn concentration. In the latter case, the manganese ions form paramagnetic clusters. At the same time, numerous centers of self-activated luminescence form in the synthesized ZnS:Mn, Mg due to mechanical stress and lattice strain. Additional annealing leads to a more uniform Mn distribution in the formed ZnS:Mn, Mg phosphor, which is accompanied by an increase in the intensity of the manganese photoluminescence band and quenching of the self-activated luminescence band.
