High Resolution Electron Microscopy In Situ Observation of Dynamic Behavior of Grain Boundaries and Interfaces at Very High Temperatures
نویسنده
چکیده
Two types of specimen-heating holder have been developed that allow one to observe, at near-atomic resolution, phenomena or reactions taking place at very high temperatures such as 1773K. The performance of the heating holders is described. Some typical examples of results obtained using these holders are given. These include formation of SIC through reaction between Si and C, growth of Sic, formation of a void at a grain boundary in SIC during sintering, surface reconstruction of Au deposited on Si, motion of the solid-liquid interface in Al,O,, and dynamic instability of a grain boundary in CuGa,.

Microstructural evolution of 304 austenitic stainless steel in friction stir welding process
Friction stir welding (FSW) was conducted on AISI 304 austenitic stainless steel plate with 2 mm thickness. The FSW was performed at a welding and rotational speeds of 50 mm/min and 400 rpm, respectively. Microstructure observations by the optical microscopy showed that a severe grain refinement occurred in the stir zone (SZ). Electron backscattered diffraction analysis (EBSD) results indicated...

Vein and hydrothermal . sedimeOI~ry types of magnesite from eastern Iran probably originated from ascending hydrothermal solutions. The cryptocryistalline magnesite is very pure although it has a variable CaO/Si02 ratio. It is compact with a very fine and uniform texture. The mineralogy of samples of dead burned magnesites calcined at different temperatures and times arc variable and can ...
متن کاملStructural and electrical properties of conducting diamond nanowires.
Conducting diamond nanowires (DNWs) films have been synthesized by N₂-based microwave plasma enhanced chemical vapor deposition. The incorporation of nitrogen into DNWs films is examined by C 1s X-ray photoemission spectroscopy and morphology of DNWs is discerned using field-emission scanning electron microscopy and transmission electron microscopy (TEM). The electron diffraction pattern, the v...

115 Abstract This article introduces the use of in situ high-resolution transmission electron microscopy (HRTEM) techniques for the study and development of nanomaterials and their properties. Specifically, it shows how in situ HRTEM (and TEM) can be used to understand diverse phenomena at the nanoscale, such as the behavior of alloy phase formation in isolated nanometer-sized particles, the me...
