Abstract

In the present work, kinetic equations of dynamic recrystallization and high-temperature deformation mechanism equations were coupled to calculate and construct processing maps for metallic alloys in 2D and 3D. The validity of this method was confirmed for selected materials (Mg and Fe alloys) by comparing the calculated processing maps with those constructed based on experimental data. The effect of the initial grain size on the processing maps was predicted. The proposed analysis method is innovative because the processing map for a material of interest can be calculated as a function of strain rate, temperature and strain under any deformation condition once the dynamic recrystallization kinetics and the creep deformation equations for the material are known. Furthermore, the proposed method can provide information regarding the rate-controlling creep deformation mechanism and microstructural evolution at any location on the processing maps.

用于计算金属合金加工图的蠕变变形机制方程和动态再结晶动力学的耦合

摘要

在目前的工作中，动态再结晶的动力学方程和高温变形机制方程相结合，以计算和构建金属合金的 2D 和 3D 加工图。通过将计算出的加工图与基于实验数据构建的加工图进行比较，证实了该方法对选定材料（镁和铁合金）的有效性。预测了初始晶粒尺寸对加工图的影响。所提出的分析方法是创新的，因为一旦知道材料的动态再结晶动力学和蠕变变形方程，就可以将感兴趣材料的加工图计算为任何变形条件下的应变速率、温度和应变的函数。此外，
