N2 - A diffusion-couple Cu/Cu-Ti alloy was prepared in order to obtain a macroscopic composition gradient in the Cu-Ti alloy system. This couple was solution treated subsequently water quenched and aged at 837 K for 600 s. The precipitation process was analyzed with an EDS-TEM. The Gibbs-Thomson relation was used to analyze the precipitation of the metastable and semicoherent β′ phase in Cu-Ti alloys and this relationship enabled us to estimate the interfacial free energy between matrix and precipitates to be about 0.31 ± 0.02 J m- 2.
