| 英文摘要 | The 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. |
