摘要：
Hybrid deposition and micro-rolling (HDMR) is a metal additive manufacturing process that integrates arc direct deposition manufacturing and micro-rolling. A two-dimensional cellular automata and finite volume method coupling model is developed for simulating the microstructure evolution of solidification and the dynamic recrystallization during HDMR forming. The influences of different rolling reductions on dynamic recrystallization fraction, average equivalent radius of recrystallized grains, and the area of dynamic recrystallization region are discussed. The results show that solidification...
