no significant variation with different Ce additions. Figure 2 shows the XRD patterns of the alloys homogenized at 300 °C for 24 h. The based alloy is composed of α-Mg matrix and AlLi phase. Additional peaks... also plays an important role in grain refinement. For the 0.5%Ce alloy, the formation of AlLi phase is greatly restrained and the amount of precipitates is relatively low. As a result, the excellent......
