Structural changes in iron powder during ball milling

2010-9-1  The XRD studies on ball milled iron powders showed that the diffraction peaks become substantially broadened after milling. The (1 1 0) Bragg peak of un-milled powder and that after 20 h of milling is shown in Fig. 1.This broadening can be attributed to reduction of crystallite size and introduction of defects (microstrain) because of milling process .
