Mechanisms and microstructure of plastic deformation in pure magnesium

ZHANG Xin-jie1,XI Yu-lin1,CHAI Dong-lang1,QI Zhi-wang2,SHI Hong-gang2 (1.School of Materials Science and Engineering, Xi’an Jiaotong University, Xi’an 710049, China; 2.Ningbo Branch of China Academy of Ordnance Science, Ningbo 315103, China)  
The influence of extrusion ratios and cooling rate on mechanisms and microstructure of plastic deformed pure magnesium was studied by optical microscopy and transmission electron microscopy (TEM). The results showed that with increasing the ratio, grain size gradually decreased, and twins became smaller and tended to disappear at last. After hot-extrusion, the rapid cooling might inhibit static recrystallization, and the microstructure of dynamic recrystallization could be retained. After hot-extruded at 380 ℃ and then compressed for 5% at room temperature, secondary twins appeared inside the primary twins. Moreover, twinning was a main deformation mechanism of pure magnesium at high temperature and room temperature.
