Abstract

A summary of the current efforts in the field of transmission electron microscopy (TEM) for the high spatial resolution characterisation needs of some of the metallurgical applications using electron diffraction techniques is presented. The aim is to highlight the improvement and the introduction of different methods in the TEM that made it possible to gain new insights in structural analyses of metals and alloys. Techniques like precession electron diffraction, electron diffraction tomography, and four-dimensional scanning transmission electron microscopy are shown to be capable of allowing an unprecedented amount of information to be studied about these materials with the help of improved detector technology. This review will showcase the benefits and some of the examples of the most recent electron diffraction applications for metals and alloys.

Metalurji Alanında Kullanılan Güncel Geçirimli Elektron Kırınımı Teknikleri

Abstract

Metalurjik uygulamaların yüksek çözünürlüklü karakterizasyon ihtiyaçları için geçirimli elektron mikroskobunda (TEM) elektron kırınımı teknikleri kullanılarak gerçekleştirilen güncel çabaların bir özeti sunulmaktadır. TEM kullanılarak metalik malzemelerin ve alaşımların yapısal karakterizasyonlarında yeni içgörüler kazandırmak için geliştirilen farklı yöntemlerin vurgulanması amaçlanmıştır. Presesyon elektron kırınımı, elektron kırınım tomografisi ve dört boyutlu taramalı geçirimli elektron mikroskopisi gibi tekniklerin yeni dedektör teknolojilerinin yardımıyla bu malzemeler hakkında benzeri görülmemiş miktarda bilginin incelenmesine olanak sağladığı gösterilmiştir. Bu derlemede, metalik malzemeler ve alaşımlar için güncel elektron kırınımı uygulamaların avantajları ve bazı çalışma örnekleri sergilenecektir.
