The breakup kinetics of Cr filaments in Cu3%Ag10%Cr (mass fraction) wire drawn in situ composites (=3.95) was monitored by quantitative metallography. Experimental results were compared with existing models and an appropriate physical model for breakup of filaments was provided. Breakup kinetics in this composite was consistent with interfacial diffusion, and the interfacial diffusion coeffcient was found to be DI(Cr in Cu(Ag)Cr interface)=47.4exp(-137 000/RT) cm2/s between 600 and 950 by Courtney's boundary splitting model, R in J/(molK).
