Microstructure evolution during reactive plasma spraying of MoSi2 with methane

Microstructures and densification of MoSi2–SiC composite by field-activated and pressure-assisted combustion synthesis

“…Nevertheless, the conclusion drawn from the equilibrium calculations [21] shows that Mo 5 Si 3 C is the equilibrium phase rather than Mo 5 Si 3 , as mentioned by several researchers, indicating that any chemical reactions that involve MoSi 2 will result in the formation of Mo 5 Si 3 as an additional reaction product [22]. In addition, it can be seen that SiC particles are agglomerate.…”

Self-propagation high-temperature synthesis and casting of Cu–MoSi2 composite

“…On matrix Cu, reinforce of MoSi 2 distribute uniformly, with regular shape of cross section. The conclusion drawn from the equilibrium calculations shows that Mo 5 Si 3 is more thermodynamically stable than MoSi 2 , indicating that any chemical reactions that involve MoSi 2 will result in the formation of Mo 5 Si 3 as an additional reaction product [21,22]. Moreover, the dual phase diagram of Mo-Si system shows that the mass fractions of Si is around 37% in MoSi 2 , 15% in Mo 5 Si 3 , and 10% in Mo 3 Si.…”

“…Droplet cooling is usually treated under the assumption of Newtonian cooling conditions (i.e., homogenous temperature inside of a droplet). [37][38][39][40][41][42][43] The droplet cooling can be described by five respective cooling stages for an eutectic binary alloy system: liquid-phase cooling, nucleation and recalescence, segregated solidification, eutectic solidification, and solid-phase cooling.…”
