Combustion synthesis of Co–Al and Ni–Al systems under reduced gravity

Combustion Synthesis: An Update

“…Also, it was concluded that the combustion temperature is not signifi cantly dependent on the gravitational level or that the ignition confi guration and low g product generally present a fi ner and more uniform microstructure. Zanotti et al reported CS of intermetallics in the Co -Al and Ni -Al systems under reduced gravity [65] . They found that under microgravity, temperatures are higher, and this is the effect that brings about improvement in the homogeneity of the product microstructure.…”

Characterization of NiAl with cobalt produced by combustion synthesis

“…There are many ways in order to produce intermetallic compounds such as self-propagating high-temperature synthesis, powder processing, casting and combustion synthesis [12]. One of the simple, fast and economic production process combustion synthesis (CS) process is based on the concept that an exothermic wave propagating in a self-sustained manner through a heterogeneous medium, is used to synthesize different advanced materials [13][14][15][16][17]. There are two modes by which CS can occur: self-propagating high-temperature synthesis (SHS) and volume combustion synthesis (VCS).…”

Combustion Synthesis of Ti3SiC2/TiC Composites from Elemental Powders under High‐Gravity Conditions

“…Many processes in combustion synthesis are affected by the gravitational level, such as melting of reactants and products, spreading of melt, coalescence of droplets, diffusion and convection in melt, buoyant force exerted on solid particles and bubbles in the melt, nucleation of solid products, crystal growth, and sample deformation. Combustion synthesis under microgravity, normal gravity, and centrifugal force has been studied, showing the effects of gravity on the propagation velocity, the product densification, and the composition segregation 7–14 …”

“…Combustion synthesis under microgravity, normal gravity, and centrifugal force has been studied, showing the effects of gravity on the propagation velocity, the product densification, and the composition segregation. [7][8][9][10][11][12][13][14] Ti 3 SiC 2 is a ternary compound that exhibits promising thermal and mechanical properties. 15,16 The synthesis of Ti 3 SiC 2 and Ti 3 SiC 2 -based composites has been conducted through different methods, 17-27 such as chemical vapor deposition, arc melting, hot isostatic pressing, SHS, reactive sintering, and mechanical alloying.…”
