Based on Hyperbolic sine relationship proposed by Sellar and Tegart rheology stress model for high-purity high-temperature plastic deformation of polycrystalline aluminum was constructed by Zenner-Hollomon parameters. Parameters influencing rheology stress of aluminum were optimized，through the initial population identification、selection、crossover、mutation、evaluation and screening, concluding the connection between rheology stress、deformation rate and deformation temperature by GA(genetic algorithm). The results show that GA is feasible, through model validation by experimental data and comparing calculated and experimental results under different deformation rates.
