Abstract：

Mg alloy plate AZ31 was formed by equal channel angular rolling(ECAR), and the influences of different ECAR processes on the microstructure and mechanical properties of Mg alloy were investigated by measuring equipment such as optical microscope, EBSD, cupping testing machine and tensile testing machine. The results show that the average grain size and the base surface texture of Mg alloy plate decreases obviously from 8.187 to 4.537 after ECAR process. Furthermore, the Erichsen value, n value and tensile strength of Mg alloy plate increase from 2.72 mm, 0.27 and 275 MPa to 4.22 mm, 0.46 and 294 MPa, respectively. In conclusion, the microstructure and mechanical properties of Mg alloy plate can be improved by ECAR process.
