Fig. 1 Microstructure of Cu-1.2Cr/2 volume percent W nanoparticles after solution heat treatment:
a SEM image at low magnification; b SEM image of the nanoparticle-rich zone; c SEM image of
the matrix; d SEM showing the locally spinodal decomposition between chromium and tungsten
Fig. 2 Variations of the microhardness with the aging time of the nanoparticle-rich zone and the
matrix of the copper–chromium (Cu–Cr)/tungsten (W) and pure Cu–Cr. (Color figure online)
