Popis: Transmission electron microscopy (TEM) can be utilized to identify some specific microstructures of metals and alloys. However, it is very difficult to precisely prepare a TEM specimen from the powder particles with several micrometers. There are more or less drawbacks in conventional preparation method. This paper describes a novel method to prepare specific specimens from the powder particles with several micrometers for TEM study. A TEM specimen approximately 5μm diameter was successfully prepared to electron transparency, which extracted from a 5μm diameter powder particle. The selected-area electron diffraction pattern (SAED) analysis was carried out.
