ADVANTAGES AND DISADVANTAGES OF DIFFERENT METHODS FOR STUDYING THE PHASE-STRUCTURAL STATES OF MATERIALS (A REVIEW)

Abstract

The paper provides a brief overview of the standard capabilities of X-ray techniques for studying materials with examples of modern performance of elemental and structural studies. X-ray research methods make it possible to reveal the elemental and phase-structural state. Thanks to modern software and electronic databases, the use of previously complex techniques is becoming simpler and more accessible. To illustrate the solution of specific problems, several examples of obtaining and decoding diffraction patterns and identifying the phase composition of the coating and ceramic material are given. An example of work in modern specialized software for acceleration and automation of phase identification is shown. For clarity, an example of identifying phases using electronic database cards is presented, which is still used today for manual decoding.  The practice of interaction between researchers shows that even specialists in the field of X-ray structural analysis are not always aware of modern methods of processing and decoding the obtained data. The possibilities and algorithm of action in research can be interesting for students, engineers, researchers of materials science and mechanical engineering profile. Keywords: microscopy, X-raystructural analysis, X-rayfluorescence analysis
