Structural characterization of MoSi2 synthesized by high-energy mechanical milling followed by annealing heat treatment

Effect of Al addition on the microstructure and low-temperature reactivity to oxygen of pre-formed MoSi2

“…The formation of a-and b-MoSi 2 during ball milling has already been reported in the open literature although most studies have concentrated on molybdenum disilicide formation starting from elemental mixtures of Mo and Si powders [27][28][29][30][31][32][33][34][35][36]. In that case, b-MoSi 2 is formed after milling of Mo and Si that are first transformed into a-MoSi 2 [34][35][36]38].…”

“…Several preparation methods have been designed specifically to take advantage of the exothermicity of the reaction. This is the case for MoSi 2 prepared by combustion and self-propagating high temperature synthesis [25,26] and by mechanical alloying [27][28][29][30][31][32][33][34][35][36].…”

Synthesis and kinetic study of (Mo,W)Si2–WSi2 nanocomposite by mechanical alloying

“…Other advantages include excellent oxidation resistance (up to 1700°C), good corrosion resistance at high temperature, hightemperature strength, and thermodynamic compatibility with many ceramic reinforcements [1,[4][5][6]. However its application is limited due to its low-temperature brittleness and oxide scale spallation, as well as low toughness and creep resistance at elevated temperature (>1200°C).…”

“…MA is a solid state reaction which is based on inducing chemical reactions of powder mixture at ambient or lower temperatures. This method has been utilized to produce a variety of non-equilibrium phases or alloys such as amorphous phases, supersaturated solid solutions, and nanostructured materials [4].…”

“…The annealing at 1000°C for 2 h caused the complete formation of MoSi 2 -Mo 5 Si 3 nanocomposite with an average size of 17 nm [26]. There were a number of investigative reports on the synthesis of monolithic MoSi 2 [4,19,21,27], as well as WSi 2 [19,27] via MA. However, the synthesis of MoSi 2 -WSi 2 via MA accompanied by post-annealing has not been reported elsewhere.…”
