X-Ray Line Broadening Analysis of Dynamic Loaded Aluminium Metal Matrix Composite

Conference paper

Abstract

The crystallite size, the residual lattice strain, the components of Gaussian and Cauchy functions of the line profiles obtained by Fourier analysis of X-diffraction lines, are correlated for a better knowledge of mechanical properties of infiltrated composites with ceramic reinforcements of different volume fractions (27, 19, 10%) and types (SiC whiskers, Al2O3 fibers and particles) after fast and slow deformation. The results are discussed taking into account the role of the reinforcing phase on the generation and relocation of dislocations along different crystallographic directions (111,200,220).
