本文研究了不同Ce含量(0.05~1.0wt.%)的Mg-1wt.%锰基合金的轧制及轧制/退火态的组织和织构。Ce的加入细化了Mg-1wt.%Mn合金的铸态和轧制/退火态组织。此外，与Mg-1wt.%Mn(M1)合金相比，轧制和轧制/退火的Mg-Mn-Ce合金的基极整体织构强度都有所减弱。织构弱化的原因是Ce在镁中的固溶度，而不是颗粒激发形核(PSN)或c/a比的变化。
In this study, the microstructures and textures of rolled and rolled/annealed Mg–1wt.%Mn-based alloys containing different levels of Ce (from 0.05 to 1.0wt.%) were examined. The Ce addition refined the as-cast and rolled/annealed grain structure of Mg–1wt.%Mn alloy. Moreover, the overall texture intensity of basal pole was weakened for rolled as well as rolled/annealed Mg–Mn–Ce alloys compared to the Mg–1wt.%Mn (M1) alloy. The texture weakening was attributed to the solid solubility of Ce in Mg rather than particle stimulated nucleation (PSN) or c/a ratio alteration.
