“…The microhardness of the as-cast Mg-0.3Ce alloy increases considerably after ECAP processing mainly due to the grain refinement as known by the Hall-Petch relationship [32]. However, besides the grain size, it was reported that the residual stress could be also an important factor in increasing the microhardness of severely deformed alloys [33,34].…”

Surface modification methods have been applied to metals and alloys to change the surface integrity, obtain superior mechanical properties, and improve service life irrespective of the field of application. In this review paper, current state-of-the-art of peening techniques are demonstrated. More specifically, classical and advanced shot peening (SP), ultrasonic impact peening (UIP), and laser shock peening (LSP) have been discussed. The effect of these techniques on mechanical properties, such as hardness, wear resistance, fatigue life, surface roughness, and corrosion resistance of various metals and alloys, are discussed. This study also reports the comparisons, advantages, challenges, and potential applications of these processes.

“…A nanocrystal surface layer about 30 μm thick was prepared on the surface of medium carbon steel by high-energy shot peening, which improved the wear resistance and decreased the friction coefficient. [13] Moreover, Zhang et al [14] found that the nanocrystals formed by USP can promote the formation of MgO patches on the wear surface, which can prevent the occurrence of thermal softening and melting in the process of high temperature and high-speed wear. Therefore, surface strengthening technology is an effective way to increase the wear resistance of metals.…”

Herein, the effect of electromagnetic shocking treatment (EST) on microstructure evolution and wear resistance of M50 steel treated by ultrasonic shot peening (USP) is investigated. The microstructure observation indicates that the EST promotes the precipitation of nanoscale carbides. The average grain size decreases slightly and the submicron grain layer increases after EST. The low‐angle grain boundaries generated by USP will transform into high‐angle grain boundaries, thereby refining the grains on the surface during EST. In addition, the surface hardness of USP‐M50 steel decreases slightly, accompanied by the reduction of surface residual stress after EST. The wear resistance results indicate that the wear loss of the EST specimens decreases by 15.7% comparedwith the specimens after USP. The improvement of wear resistance induced by EST is attributed to the increased fine precipitations. These precipitations hinder the grinding of abrasive particles into the matrix and connect with wear debris and oxide particles to form well consolidated self‐lubricating films to prevent wear losses. The refinement of surface structure is another important reason for the improvement of wear resistance.
