MoAlB as a typical member of MAB phases has attracted much-growing attention due to its unique properties. However, the low production powders limits further development and potential applications. In present work, ultra-fast preparation high-purity in few seconds is achieved by self-propagating high-temperature synthesis (SHS) using raw powder mixture at an atomic ratio Mo : Al B = 1 1.3 1. SH...

The possibility of obtaining sialon in the SHS-Az mode (self-propagating high-temperature synthesis using sodium azide) from systems "silicon dioxide – azide aluminum halogenide silicon" is viewed. phase composition and combustion products are analyzed average particle size determined. It was found that particles a product were combined into agglomerates. plate-like 300...350 nm, equiaxed 120.....

This paper is the continuation of our previous paper. In this work, we optimized synthesis aluminum borides by SHS method. The purpose research was to develop foundations waste-free technology. initial components were powders boric anhydride (B2O3), (Al), oxide-heating additive (KNO3), various fluxing additives, including mixed ones. optimal ratios for increasing yield boride with a high boron ...

It has been shown that defect-free Stone–Wales (SW) free few-layer graphene (FLG) can be obtained by carbonizing lignin under conditions of self-propagating high-temperature synthesis (SHS). The was used as a modifying additive for pyrotechnic compositions. found the addition 2.5 mass % synthesized from to complex based on porous silicon and fluoropolymer leads significant increase in combustio...

The paper presents the research results on produsing by method of liquid-phase self-propagating high-temperature synthesis (SHS) composite metal-matrix alloys intended for obtaining wear-resistant coatings electric spark deposition (ESD). Oxides NiO, Cr 2 O 3 and mineral concentrate ZrO were used as a melting charge. Alloys based Ni-Al system with aluminides complex composition containing Zr ob...

Cast refractory alloys Mo–Nb–Si–B were prepared by centrifugal self-propagating high-temperature synthesis (SHS) from metallothermic mixtures containing MoO3, Nb2O5, Al, Si, and B powders, additive of Al2O3 as a temperature-moderating chemically inert agent. Variation in the acceleration amount affected composition structure cast alloys. In wide range values, combustion temperature was found to...

the molybdenum dicilicide is an intermetallic compound with two allotropies tetragonal ?-mosi2 and hexagonal ?-mosi2.the ?-mosi2 phase is established to 1900 ?c and ?-mosi2 phase from 1900 to 2050 ?c. this material has considerable properties that provide different applications in different industries such as air-space industry and gas turbines. the molybdenum synthesis can be down in various w...
