| Abstract | In this work, the microstructural evolution and mechanical properties of a pre-deformed WE43 magnesium alloy when aged at 250 and 300 degrees C were further investigated. It is found that the abundant deformation twins introduced by pre-deformation were maintained within the alloy during the aging treatment. Second particles formed at the twin boundaries and coarsened with aging time, especially at 300 degrees C. When peak-aged at 250 degrees C, the fine metastable beta''' and beta' precipitates formed in the un-deformed alloy have been transformed into relatively large beta(1) and beta precipitates by the pre-deformation. While peak-aged at 300 degrees C, the pre-deformation obviously refined the beta precipitates. Mechanical properties indicate that pre-deformation can increase the yield strength by 19 MPa and 54 MPa for the peak-aged alloy at 250 degrees C and 300 degrees C, respectively, and will not obviously deteriorate the tensile elongations.
