Abstract：
The results suggested that the repeated plastic deformation (RPW) process prior to hot extrusion has a great effect on improving ageing response of the as-extruded Mg-6Zn-1Er alloy. The rod-like beta＇(1), phase was promoted to precipitate abundantly during isothermal ageing treatment, which mostly contributed to the highest peak hardness of 98.6 (+/- 2.0)HV in the alloy treated by 300 repeated plastic working circles. Furthermore, the peak-aged alloy displayed the highest tensile strength, and the values of the ultimate tensile strength and yield tensile strength were about 360 MPa and 252 MPa, respectively.
