The roughness retention ability of the work roll surface during the cold rolling process is of great significance, especially in the production of the high-quality rolling section. Laser shock peening (LSP) is an advanced and effective surface treatment technique to improve the fatigue life, wear resistance, and other mechanical characteristics of metal components. Current studies commonly examined the reinforcement effect of single and multiple LSP treatments on Cr5 steel samples through XRD analysis, hardness testing, and residual stress measurements of different parameters. In addition, the abrasion test is widely conducted to determine the wear resistance. Compared to unprocessed samples, LSP could promote grain refinement and thus significantly increase the hardness and residual stress. Furthermore, the slight decrease in surface roughness shows that LSP treatment is an effective approach to slowing down the roughness decline rate and prolonging the roller service life. It is also found that multiple LSP impacts could remarkably improve the surface roughness retention of Cr5 steel, in which the optimal laser power density was around 23 GW/cm2.

Effect of heat treatment (HT) on T15 high‐speed steel (HSS) prepared by hot isostatic pressing (HIP) and forging processes using electrode induction melting gas atomization powder is successfully studied; their microstructure, friction, and wear properties are in comparison. The lowest friction coefficient and wear rate are achieved in the forging plus HT T15 HSS. Simultaneously, the minimum wear profile depth and dimension are also obtained in the forging plus HT one. The prior particle boundaries produced by HIP are overtly eliminated, and the grains are refined and evenly distributed after forging and HT processes. The refined microstructure after forging plus HT promotes improvement of friction and wear performance. Wear mechanisms for samples prepared by different processes are discussed. The microstructure is characterized by high‐angle angular dark field‐scanning transmission electron microscopy, scanning electron microscopy, and white light interferometer. This work proves that HSS products with high wear properties can be prepared by appropriate HIP + forging + HT processes.
