| 摘 要： | Microstructure evolution of ZK60 magnesium alloy deformed at 023 hoy cyclic extrusion compression （CEC） large deformation method was investigated. ZK60 alloy was deformed in the range of accumulated true strain of 0.8-17. The microstructure of evolution was investigated by optical microscope （OM） and transmission electron microscopy （TEM）. The results show that microstructure is obviously refined, and homogenous equiaxed microstructure is achieved in the entire range of the examined deformations by subjected to CEC deformation. By increasing the accumulated strain to 17, the grain size decreases into sub-micron regime with about several hundred nanometers. The mechanism of grain refinement in ZK60 alloy by CEC can be attributed to continuous dynamic recovery and recrystallization.
