Abstract

In the present work, an approximation novel method was used to determine both the crystallite size and micro-strain from XRD profile for deformed and non-deformed 3004 Al alloy by determining the total physical broadening, the crystallite size broadening and the strain broadening. Aluminum and its alloys are widely used in aircraft automotive and in construction industries because of their desirable physical properties. The estimated crystallite size and micro-strain obtained via this approximation method were in a good agreement with the full width at half maximum (FWHM) and the strain broadening at each peak (111), (200), (220), (311), (222) at the corresponding Bragg angles. The variation of strain broadening, defect density and stored dislocation energy with thickness reduction seems to be an exponential growth, according to the increasing of the dislocation density as predicted theoretically.
