The magnetic properties and the crystallization and its influence on the magnetic and struc- tural properties for rapidly quenched amorphous Nd_6Fe_(81)B-(13) alloy have been studied.The low temperature magnetic properties,the Curie temperature and the crystallization behavior are discussed.A small addition(6at.-%)of Nd in amorphous Fe-B alloys increases largely the crystallization temperature T_x but causes a decrease of the Curie temperature Tc·A new phase was observed in the sample annealed at 873 K.

CURRENT STATUS OF HIGH-RESOLUTION ELECTRON-MICROSCOPY AND ITS APPLICATIONS TO MATERIALS SCIENCE AND CONDENSED MATTER PHYSICS

材料科学技术（英文）

The present paper summarizes the current status of high resolution elect;on microscopy ( HREM) and the applications of HREM to materials science and condensed matter physics. This review recounts the latest development of high resolution electron microscope, progress of HREM and the applications of HREM, including the crystal structure determination of microcrystalline materials and characterization of the local structure of the defects and nanostructured materials as well as qualitative and quantitative analysis of the grain boundaries, interfaces and interfacial reactions in the advanced materials by means of HREM in combination with electron diffraction, subnanometer level analysis, image simulation and image processing.
