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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
