Combustion synthesis of ceramic and metal-matrix composites [PDF]

Combustion synthesis or self-propagating high temperature synthesis (SHS) is effected by heating a reactant mixture, to above the ignition temperature (Tig) whereupon an exothermic reaction is initiated which produces a maximum or combustion temperature,

Nanocalorimetry of Nanoscaled Ni/Al Multilayer Films: On the Methodology to Determine Reaction Kinetics for Highly Reactive Films

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
Free‐standing Ni/Al multilayer thin films are investigated with a novel commercial nanocalorimeter and a conventional calorimeter. The Kissinger analysis shows a monotonic Arrhenius behavior over the entire five orders of magnitude of heating rates for all thermal events.

RuAl Thin‐Film Deposition by DC Magnetron Sputtering

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
The synthesis and influence of deposition parameters on the corresponding microstructure of single‐phase RuAl in B2 structure is examined via transmission electron microscopy analysis and X‐ray diffraction with additional pole figure measurements. These are correlated to mechanical properties of the magnetron‐sputtered thin films.

Mechanical Ignition of Al/Ni Reactive Multilayer Systems: Influence of Impacting Material, Its Properties, and Geometric Characteristics

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
Reactive multilayer systems (RMS) show a high tendency for a self‐propagating reaction through the application of kinetic energy. The kinetic energy is not applied directly to the RMS, but to a particle distribution, where the penetrating particles have different characteristics in terms of their geometry as well as their mechanical and thermal ...

Facile Mechanochemical Synthesis of Compositionally Complex Spinel‐type Oxides, (Co, Fe, Mn)3O4, (Co, Fe, Mn, Ni)3O4, and (Co, Cr, Fe, Mn, Ni)3O4

Zeitschrift für anorganische und allgemeine Chemie, Volume 650, Issue 23, December 2, 2024.
Abstract In the current work, a simple mechanochemical route has been employed to preparatively access three spinel‐type compositionally complex ceramics, i. e., (Co, Fe, Mn)3O4, (Co, Fe, Mn, Ni)3O4, and (Co, Cr, Fe, Mn, Ni)3O4. Hydrated nitrate salts of the respective transition metal elements were mechanically ground with ammonium hydrogen carbonate.
