✦ Synopsis

On the basis of the principle of Warren-Averbach X-ray diffraction profile analysis, an accurate and rapid method of broadened X-ray diffraction profile analysis characterized by the use of a Voigtlike function for profile fitting and by a new modellization of the real part of the Fourier coefficients has been developed. The purpose of this study is to link the mechanical macroscopic properties (hardness, ultimate tensile strength, coM work) of the studied materials with profile analysis parameters, such as the integral peak width, the average coherent domain size and the distortion factor, and also to study the influence of external loading on plastic deformation of materials. Two applications have been realized: firstly a low alloyed carbon steel (0.35%C-1%Cr) quenched and tempered at various temperatures was studied, and secondly a nickel-alloyed steel (9% Ni) deformed by traction (0.36%-10%) or by torsion (5%-150%) has been analysed.
