Abstract: Melting behavior of the reaction products during a thermite-type combustion synthesis of Ni-25 mol%Al alloy (Ni3Al) has been investigated. The thermite-type combustion synthesis reaction is represented by the following equation: 3aNiO+3(1−a)Ni+(1+2a)Al=Ni3Al+aAl2O3. In this process, the reaction temperature can be varied arbitrarily by changing the value of a. The reaction sequence and the melting behavior of the products are summarized as follows: (1) The thermite-type combustion synthesis reaction of Ni3Al is a two-step reaction of the combustion synthesis reaction between Ni and Al; and the thermite reaction between the Ni-Al melt and NiO. (2) When the temperature of the specimen rises over the melting temperature of NiAl at the first reaction stage, the thermite reaction takes place and then the fluid products are produced
