晶粒细化机制
Grain refinement mechanismThe process by which ultrasonic vibrations applied during the deposition stage of wire arc additive manufacturing (WAAM) promote the nucleation and growth control of alloy steel grains, resulting in a refined microstructure. / 超声波振动在电弧增材制造沉积阶段促进合金钢晶粒成核和生长控制的过程，从而产生细化的微观组织。
