Mechanical alloying produces nonequilibrium phases such as supersaturated solid solutions, nanocrystals, quasicrystalline, amorphous phases, and so on. The maximum supersaturated solid solubility of carbon in mechanically alloyed copper was reported by Saji et al. The value was 28.5 at. pct C, which was much larger compared with the equilibrium solid solubility of 0.04 at. pct C in copper at 1373 K reported by McLellan in 1969. On the other hand, the equilibrium solid solubility of carbon in a Cu-Zn alloy is not reported yet, and it is estimated to be small compared with those in copper and zinc. In this study, the maximum supersaturated solid solubility of carbon in the mechanically alloyed Cu-Zn alloy is measured from the lattice parameters obtained from X-ray diffraction.
