一、引言 自1945年Purcell和Bloch发现了大块物质中的核磁共振(NMR)以来,已形成了三个分支,分别应用于分子化学、非金属固体和金属合金。其中第一个分支发展最早,已有精良的装备,成为化工生产和化学研究中的重要工具。第二分支发展也很快,包括如NMR成像等新技术的应用。第三分支中虽也有了高质量的商品设备,但大多数实验都采用自制的仪器。本文重点介绍NMR在合金研究的某些特殊应用。 I. INTRODUCTION Since Purcell and Bloch discovered the nuclear magnetic resonance (NMR) in bulk materials in 1945, three branches have been formed and applied to molecular chemistry, non-metallic solid and metal alloys, respectively. The first branch of the development of the earliest, well-equipped, as chemical production and chemical research an important tool. The second branch is also rapidly developing, including new technologies such as NMR imaging. Although the third branch also has high-quality goods and equipment, but most of the experiments using homemade equipment. This article highlights some of the special applications of NMR in alloy research.
