Sažetak
The strengthening of the Cu-10 wt.% Ni-4 wt. % Sn supersaturated solid solution during ageing was followed by hardness measurement. The corresponding changes in structure were followed by optical microscopy and x-ray diffraction. After initial fast increase in hardness caused by spinodal decomposition a maximum in hardness is reached that corresponds to a decomposition of the matrix into two f.c.c. structures with different lattice parameters. The decrease in hardness after longer ageing times is caused by discontinuous precipitation of equilibrium a + y phase and recrystallisation of the matrix.
