N2 - Atmospheric-controlled induction-heating fine particle peening (AIH-FPP) was performed for low-alloy steel, and the effects of the peening temperature, the microstructure of steel, and thermal history during AIH-FPP on the resultant microstructure of treated steel were investigated. Regardless of the prior microstructure and thermal history, the grains near the surfaces were refined by AIH-FPP at peening temperatures from 923 K to 1023 K owing to dynamic recrystallization. To examine the effect of AIH-FPP on the fatigue properties of steel, plane-bending fatigue tests were performed. Compared with the steel mirror-polished, treated with FPP at RT, or only induction-heated, the fatigue properties of steel treated with AIH-FPP were improved. This is because of the formation of a thick and uniform grain-refined layer, the generation of compressive residual stress, and hardening of the surface by AIH-FPP. Moreover, owing to the grain refinement progress, the fatigue properties of steel improved with increasing peening temperature.
