许多研究表明，在含有稀土（RE）元素和锌的合金中发现了基面排列不太明显的织构和相关的可成形性改善。然而，这些附加元素的组合对纹理修改的影响尚未被清楚地理解。在这项工作中，从Mg-Zn-RE合金在400 °C轧制的板材样品用于在不同温度下拉伸载荷下的原位同步辐射X射线衍射测量，以跟踪变形过程中衍射轮廓和织构的发展。在Mg-Zn-RE合金中，观察到在高温变形过程中的回复和动态再结晶的显着延迟相比，无RE的Mg-Zn合金。从织构变化的角度评述了主动变形机制和动态再结晶机制的差异。为了讨论不同机制的影响，EBSD观察揭示了微观结构的发展。
Many studies have shown that textures with less distinct alignment of basal planes and the related improvement of formability are found in alloys that contain rare-earth (RE) elements and zinc. However, the effect of the combination of these additional elements on the texture modification has not been yet clearly understood. In this work, sheet samples from Mg–Zn–RE alloys rolled at 400 °C were used for in situ synchrotron X-rays diffraction measurements under tensile loading at different temperatures, in order to track the development of diffraction profiles and textures during deformation. In Mg–Zn–RE alloys, a significantly retardation of recovery and dynamic recrystallization during the high temperature deformation is observed in comparison to the RE-free Mg–Zn alloy. The differences in the active deformation mechanisms as well as the dynamic recrystallization mechanisms are reviewed with respect to the texture alteration. For discussion of the impact of different mechanisms, EBSD observations reveal the microstructure development.
