Adiabatic temperature of combustion synthesis of Al–Ni systems

The adiabatic reaction temperature of stoichiometric Ni+Al and 3Ni+Al elemental mixtures and non-stoichiometric Ni/Al reaction systems under various initial conditions are calculated and compared with experiments. The experiments are based on the measurement of temperature–time profiles of the combustion reactions carried out in a nearly adiabatic condition. The adiabatic reaction temperature changes with the fraction of Ni with a maximum at about equal atomic ratio. The experimental results are in good agreement with the calculations.
