Notes:
The present communication is concerned with the interdiffusion kinetics and the interfacebreakdown that take place in the Nb/NbC multilayer system as the result of thermal annealing in the400-800oC temperature range. Within this temperature range carbon is the diffusing species. Carbondiffuses from the carbide layer into the adjacent Nb layer, depleting its concentration within the carbide,causing the nucleation and subsequent growth of an intermediate Nb2C layer and decreasing the width ofthe original Nb layer. TEM examination of the cross-sections of the multilayer specimens provides dataregarding the evolution of the microstructure and, in particular, regarding the initial nucleation stage ofthe newly formed Nb2C layer
