THERMODYNAMICS ANALYSIS OF FLOWING FOR SHS-REACTIONS
IN SYSTEM «NICKEL-ALUMINIUM»
Zaporozhe state engineering academy
The article is devoted to the thermodynamic analysis of the reactions that are possible
at the preparation of intermetallic nickel-aluminum alloys in self-propagating hightemperature
synthesis (SHS). Thermodynamic analysis showed that for nickel-aluminum
system adiabatic combustion temperature is at the melting point of the final product - the
intermetallic compound, which is a sufficient condition for the occurrence of SHS-reaction
at normal conditions. Also, on base of thermodynamic analysis, the established sequence
of SHS-reactions leading to the formation of nickel-aluminum alloys, which contributes to
the elucidation of the mechanism of the process.
