High-resolution transmission electron microscopy (HRTEM): image processing analysis of defects and grain boundaries in nanocrystalline materials

A brief overview of the application of the high resolution transmision electron microscopy (HRTEM) method is given: the principle of HRTEM image formation in an electrone microscope; different modes of image formation; the role of the contrast transfer function in HRTEM image formation; definition and improvement of electron microscope resolution. In theis work the results obtained by applying the CRISP program to analyse the HRTEM photopgraphs of mechanically allyed nanocrystalline materials are presented.
