In recent years, the performance of transmission electron microscopes has been improved. In particular, the emergence of field emission permits observation of the analytical electron microscopy (FE-AEM) arrangement of individual atoms, and the identification of the chemical composition of a microregion of the order of Inm. This report summarizes the characteristics of FE-AEM. As an application to metal materials, the report briefly describes the results of FE-AEM analysis of a segregation of alloying elements in newly developed pearlitic steel wire with a strength of 2000 MPa. and the structure of ultrafine precipitates in AI-Mg-Si alloys.
