摘要

本研究利用现场辅助烧结技术（FAST）研究了商用纯镁（Mg）的烧结机理。FSEM 和 XRD 分析确定了受颗粒几何形状、残余应力和通过机械研磨形成的微观结构影响的四种不同的结合和烧结机制。XRD 分析表明，晶粒大小和晶格微应变随研磨时间的增加而变化。机械研磨和 FAST 的结合对镁粉的微观结构和机械性能有显著影响，其中 Mg36 样品显示出良好的强度和硬度。

Effects of Mechanical Milling and FAST Sintering on Mg Powders: Microstructural Analysis and Mechanical Properties

This study investigates the sintering mechanism of commercially pure Magnesium (Mg) using the Field Assisted Sintering Technique (FAST). FSEM and XRD analysis identified four distinct bonding and sintering mechanisms influenced by particle geometry, residual stress, and microstructure developed through mechanical milling. XRD analysis demonstrated variations in crystallite size and lattice micro-strain with increasing milling time. The combination of mechanical milling and FAST exhibited significant effects on the microstructural and mechanical properties of Mg powders, with the Mg36 sample displaying promising strength and hardness.
