Advance in Research on Solid-Solid Interfacial Reaction in Mo-Al System

In this paper choosing the Mo-Al system,by the idea of plotting the solid state phases,the evolvement of the incubation period and species of primary phase of interfacial reaction products are introduced during Mo-Al solid-solid interfacial reactions from the related theory and experiment,respectively.Owing to interfacial reactions being controlled by the thermodynamic,kinetics factors,size of Mo-Al system and concentration etc,the reasonable results cannot be gotten by the classical thermodynamics,so some compounds of Mo-Al : Mo3Al8、MoAl4、MoAl5、MoAl6、MoAl12 are all likely to be the primary phase.
