AbstractThe effect of shot peening (SP) on microstructure and hardness of ultrafine-grained (UFG) low-alloy steel was investigated. With increasing shot-peening time from 0.5 to 1.5 h, grain size of UFG low-alloy steel decreases from 400 to 280 nm at surface whilst that of the layer with a depth of 160 m decreases from (230 +/- 15) to (75 +/- 5) nm. Interestingly, nanoindentation shows that hardness increases linearly with increasing the SP duration, reaching a value as high as (7.10 +/- 0.1) GPa at the depth of 160 mu m after the SP duration of 1.5 h. The thickness of the SP treated layer is measured as similar to 300 mu m. The Hall-Petch (H-P) relationship was established for the hardening layer. Correspondingly, abrasion resistance should be similar to 51% higher than that of as-prepared UFG low-alloy steel. As shown in SP processing, grain refinement is the key factor responsible for the strengthening of the studied steel.

The thickness of the SP treated layer is measured as ~300 lm. The Hall–Petch (H–P) relationship was established for the hardening layer. Correspondingly, abrasion resistance should be ~ 51 %higher than that of as-prepared UFG low-alloy steel. As shown in SP processing, grain refinement is the key factor responsible for the strengthening of the studied steel.
