摘要
An irreversible thermodynamics model was constructed to study the combination reaction of two heterogeneous pure metals in diffusion bonding based on the theorem of minimum entropy production and the Curie principle.The correlation between the irreversible reaction and diffusion was discussed,which provided the kinetic inevitability of an incubation period of a primary phase.The analytical descriptions of the incubation period and the kinetically critical grain size of the primary phase were deduced.Comparison of the experimental results of Al/Mo interfacial reaction with the calculations indicated that the performed theoretical analysis was reliable.
