摘要: Abstract Nano-Fe powders could be prepared only after 10 hours of ball milling assisted by dielectric barrier discharge (DBD), whose particle mean size was about 100 nm. The synergetic refinement mechanism DBD on had been investigated examining the morphology Fe powder using scanning electron microscopy and transmission microscope. It shown through SEM that particles displayed an extraordinary plasticity in early stages under action DBD, plastic deformation more severe than normal milling. Large quantity 50 nm were observed TEM which generated during owing to hot explosion effect caused bombardment. indicated promoted synergy superplasticity, huge pulsating stress high-energy
