Beschreibung

nach der Bestellung gedruckt Neuware - Printed after ordering - Defect and Microstructure Analysis by Diffraction looks at a key aspect of state-of-the-art methods for analyzing the actual structure of materials. Diffraction analysis is typically based on idealized crystals. The impurities and irregularities that work themselves into virtually all crystalstructures, however, cause diffraction peak profiles to broaden and sometimes become asymmetric, making the data difficult to interpret. More powerful methods are undoing this effect, using the discrepancies themselves to describe microstructure of the material with unprecedented accuracy. Thesetechniques in turn play a key role in many of the evolving techniques for microstructure analysis from diffraction patterns such as micro-strain, crystallite size, macro-strain and preferred orientation analysis. This book provides a comprehensive analysis of the fundamental theory and techniquesfor microstructure analysis from diffraction patterns and summarizes the current state of the art. It lays the foundation for the next and last major development in this field: the extraction of the full information in a powder pattern by the simulation of the full experimental pattern. The goal ofthis research is to extract all of the information locked in the powder diffraction pattern including the types and densities of stacking faults, the strain field produced by each, the anisotropic crystallite size and orientation, along with the size and strain distributions of each phase in aspecimen.

Über diesen Titel

Inhaltsangabe

Defect and Microstructure Analysis by Diffraction is focused on extracting information on the real structure of materials from their diffraction patterns. The primary features of a powder diffraction pattern are determined by the "idealized" periodic nature of the crystal structure. With the advent of computer automation the techniques for carrying out qualitative, quantitative and structure analysis based on the primary pattern features rapidly matured. In general, the deviations of a particular specimen, from the ideal or perfect crystal structure, cause diffraction peak profiles to broaden and sometimes to become asymmetric. Thus, information on the real structure or microstructure of a specimen can be obtained from a careful study of the diffraction line profiles. The evolving techniques for microstructure analysis from diffraction patterns such as micro-strain, crystallite size, macro-strain and preferred orientation analysis require an ever more detailed understanding of the effects of crystallographic mistakes on peak assymmetry and the effect of the distribution of small crystallites on the tails of diffraction peaks. This book provides a comprehensive analysis of the fundamental theory and techniques for microstructure analysis from diffraction patterns and summarizes the current state of the art. This complete survey lays the foundation for the next and last major development in this field: the extraction of the full information in a powder pattern by the simulation of the full experimental pattern. The goal of this branch of science is to extract all of the information locked in the powder diffraction pattern including: the types and densities of stacking faults, the strain field produced by each, the anisotropic crystallite size and orientation, along with the size and strain distributions of each phase in a specimen. This book provides a complete summary of the developments of the twentieth century and points the way.
