The papers from the 14th International Conference on Shot Peening (ICSP14) are now available at www.shotpeening.org.
More than 90 scientific presentations were discussed during conference in Milan, Italy in September 2022. One of the subjects that attracted great interest is the application of shot peening as a post-treatment for additive manufactured parts. The great diffusion and development of additive manufacturing and the quality of the surfaces that are obtained requires the definition of new approaches and new sets of parameters to successfully apply shot peening. The studies presented on Al alloys, Ti alloys, Inconel, stainless steels, as well as the methods developed for assessing the improvement of the fatigue endurance and strength of additive manufactured parts, attracted the interest and the curiosity of the audience with many questions and interesting discussions.
In the session dedicated to laser shock peening (LSP), organized by Domenico Furfari, more than twenty presentations were presented, giving a 360˚ view on the most recent developments of this treatment. Interesting talks addressing multiple aspects of the treatment were given including tailored laser peening to anisotropic residual stresses, fast laser peening, the application of nanoindentation for residual stress measurement, the application of laser peening to improve the corrosion resistance of aluminium alloys, and many more.
The traditional sessions dedicated to fatigue, experimental analysis, process development and case studies exhibited the multiple applications of shot peening and its flexibility in new industrial environments, confirming the increasing interest for the treatment and showing the innovative solutions developed in the last few years.
Modelling of shot peening was another successful session. It is interesting to underline that until a few years ago, the simulations were done mainly to assess the final residual stress state. Now there is a great effort devoted to more comprehensive simulations that can assess the final surface finishing and the microstructural modifications after shot peening.
Finally, there were sessions dedicated to other peening processes. The session dedicated to characterization of shot peening showed alternative ways to peen materials, such as cavitation peening or acoustic peening, that can be used in special applications. New methods for a more accurate characterization of the treatment were presented.
