• Investigation of microstructural changes in pure commercial-grade iron caused by fine particle peening (FPP) treatment was undertaken by detailed observation using field emission-scanning electron microscopy (FE-SEM) and measurement of the X-ray diffraction peak full width at half maximum (FWHM). The effect of pre-FPP treatment on the oxygen diffusion process within iron is also discussed. FPP treatment produced stratification patterns with many dislocations and grain boundaries on the treated surface. This unique microstructure strongly affected the diffusion capacity, so that thicker oxygen-concentrated layers were observed on pre-FPP/oxygen diffusion-treated surfaces.
