“…The age hardening behaviour under such condition is reported in Fig. 1, showing that a saturation of the hardness is reached after 10h (155 HV ± 8), in good agreement with published data on similar alloys [5,6]. The Vickers micro hardness of the alloy was measured with a BUEHLER Micromet 2003 machine, using a 300 g load (2.94 N), each plotted value being the average of ten measurements.…”

The early stage of the chromium precipitation in copper was analyzed at the atomic scale by Atom Probe Tomography (APT). Quantitative data about the precipitate size, 3D shape, density, composition and volume fraction were obtained in a Cu-1Cr-0.1Zr (wt.%) commercial alloy aged at 713K. Surprisingly, nanoscaled precipitates exhibit various shapes (spherical, plates and ellipsoid) and contain a large amount of Cu (up to 50%), in contradiction with the equilibrium Cu-Cr phase diagram. APT data also show that some impurities (Fe) may segregate along Cu/Cr interfaces. The concomitant evolution of the precipitate shape and composition as a function of the aging time is discussed. A special emphasis is given on the competition between interfacial and elastic energy and on the role of Fe segregation.
