摘要目前，镁合金在结构和功能方面的应用引起了人们的极大兴趣。镁合金是一种轻质材料(1.7-2.0g/cm3)，其密度明显低于钛合金和不锈钢。此外，从生物医学装置的角度来看，它们是可生物降解的、可生物吸收的和生物兼容的。本工作的目的是研究铸态合金在三轴锻造过程中晶界析出行为向纳米析出行为的转变，特别是探索小角X射线散射技术在纳米析出研究中的应用，并与传统的X射线衍射和电子显微镜的方法进行补充。
ABSTRACT Currently, there is a significant interest in magnesium (Mg) alloys for structural and functional applications. Mg alloys are lightweight materials (1.7–2.0 g/cm3), whose density is significantly lesser than that of titanium alloys and stainless steels. Furthermore, from the perspective of biomedical devices, they are biodegradable, bioresorbable and biocompatible. The objective of this work is to investigate the transition from grain boundary precipitation behaviour in the as-cast alloy to nanoscale precipitation during triaxial forging, with particular emphasis on exploring the application of small-angle X-ray scattering technique to investigate nanoscale precipitation and complement with the conventional approach of X-ray diffraction and electron microscopy.
