Mechanical activation-assisted solid-state combustion synthesis of in situ aluminum matrix hybrid (Al3Ni/Al2O3) nanocomposites

Microanalysis on CuInSe2 compound synthesized by mechanochemical processing

“…As a result, the interfacial area increased, clean interfaces exposed and the defect density increased, which would allow the diffusion along defects. So this minimum Tad was reduced to approximately 1300 K during milling [9,10]. Literature values of calculated enthalpy formation for CuInSe 2 , H f (CuInSe 2 ) = −218.50 kJ/mol [11], Gmelin and Hönle had determined the molar heat capacity of CuInSe 2 , Cp (298.15 K) = 99.82 J/(mol K) [12].…”

Nano and hybrid aluminum based metal matrix composites: an overview

“…Zhang et al [10], Sureshbabu et al [11], Feng et al [12] and Geng et al [34] have used squeeze casting to fabricate Al based hybrid composite which distribute nano particles homogeneously that increased strength and resistance to fracture propagation. Reddy et al [35] produced aluminium matrix hybrid (Al 3 Ni/Al 2 O 3 ) nano composite by mechanically activated solid state combustion in-situ method without affecting nano-structure. It was reported that in-situ processed composite are technologically considered to be more advanced composites than ex-situ processed composite materials.…”

Combustion of heterogeneous nanostructural systems (Review)

“…Mechanical activation is used for these systems to obtain either fine-grain (nanocrystalline) products, for instance, the Al 3 Ni/Al 2 O 3 nanocomposite [72], or a superactive thermite composition. The latter circumstance is closely related to the above-considered nanothermites (superthermites), where mechanical activation is used as a method for obtaining nanothermites [72][73][74][75][76]. For this purpose, first, the critical time necessary for selfignition of the Me 1 + Me 2 O x system during mechanical mixing is determined (usually, tens of minutes).…”
