Abstract:
The reactive mechanism of XD method for synthesizing a NiAl matrix composite has been studied by means of DTA, XRD and SEM. Results show that the reactive mechanism is an overlap of combustion waves produced by SHS reactions which are ignited by exothermic reactions between and in the high energy state. The density is one of the important factors which determine the reactive mechanism because the contact porosity may obstruct ignition and propagation of the combustion wave.
Key words: NiAl matrix composite, XD method, reactive mechanism
