Tensile specimens of the Al-Cu alloys containing 5.6 to 33.4 wt.% Cu were deformed to failure for investigating the effects of strain rate, test temperature, initial grain size and the volume fraction of θ phase on ductility, grain growth and cavitation level. The ductility increases with the increase in temperature and decrease in grain size. The other variables, however, influence the ductility more in an interdependent manner. There occur grain growth and cavitation to varying extent depending on test condition; but the latter appears to show a systematic effect in limiting the ductility.
