Influence of Process Parameters on Surface Hardening in Hammer Peening and Deep Rolling.

Abstract

Abstract: Deep Rolling and Machine Hammer Peening are mechanical surface treatments which generate hard surfaces due to cold working accompanied by the induction of compressive residual stresses. Both processes can be controlled by a variety of parameters. Up to this point, it is unclear which parameters should be used to generate hard surfaces. This paper gives a statistical approach to close this gap. Four different materials, containing 1.2379, GP4M, EN-GJL-250 and EN-JS2070, are tested using brinell hardness measurement and for each material every machining parameter is investigated. In addition an approach is given why a large ball diameter in deep rolling results in a higher hardness than a small diameter using a kinematic isotropic material FEM model of 1.2379.
