... Abstract This chapter discusses surface engineering treatments, including flame hardening, induction hardening, high-energy beam hardening, laser melting, and shot peening. It describes the basic implementation of each method, the materials for which they are suited, and their effect on surface...

... Abstract Mechanical treatments such as grinding and shot peening are often employed in the production of case-carburized parts. Grinding, besides restoring precision, removes carbide films, internal oxidation, and high-temperature transformation products. Shot peening strengthens component...

If the decarburization is shallow, can it be grit blasted in the critical areas to remove the affected layer and shot peened...

... martensite can be altered by subzero treatment after quenching. Cold working by either peening or rolling can modify the surface microstructures and have significant bearing on the life of the component, as too can surface grinding. One must not overlook the value of the microstructure and properties of...

..., such as shot peening or surface rolling. Retained austenite, being relatively soft, is work hardened by these processes with the added benefit that the surface residual stresses are made more compressive. It is important, however, that the balancing tensile residual stresses do not peak just beneath...

For some applications, shot peening might counter some of the adverse effects of a coarse-grained structure (although no data are available to show this...

Indeed, there are a number of manufacturing processes in which the sole purpose is to introduce beneficial residual stress patterns in critical parts. These processes include case hardening, shot peening, and surface rolling. On the other hand...
