Ageing hardness for 6063 Aluminium alloys has been predicted

and the effects of ageing process parameters on ageing hardness have been studied by means of artificial neural network.The results show: in the range of temperature and time of this study

the temperature and time of the first-staged ageing process and the time of the second-staged ageing process have less influence on ageing hardness

but the temperature of the second-staged ageing process has obvious influence on ageing hardness.This result accords with that of orthogonal experiment.Through combining artificial neural network and orthogonal experiment

the optimum two-staged ageing process parameters are 170 ℃ for 70 mins and 210 ℃ for 50 mins.
