本文报道了200多次AA 2024合金挤压试验的分析结果。建立了不同截面形状的压力和速度限制，它表明，通过将一个新的形状因子，这些可以预测具有一定的精度。对挤压过程中的再结晶动力学进行了分析，理论模型与实验结果吻合较好。提出了描述各阶段结构发展的半经验公式。MST/1725
AbstractThe analysis of over 200 extrusion trials on alloy AA 2024 is reported. The pressure and speed limitations for varying section shapes are established, and it is shown that by incorporating a novel shape factor these may be predicted with some accuracy. The recrystallisation kinetics in the extrusion process are analysed, and the theoretical form is shown to fit the experimental results well. Semiempirical formulae are presented to describe the development of structure at each stage of the process.MST/1725
