Manufacturing‐induced material properties of linear flow split and linear bend split profiles

Abstract

In this work the two massive forming processes linear flow splitting and linear bend splitting, which generate profiles from sheet metal, are evaluated with respect to characteristic manufacturing‐induced material properties of the produced parts. Resulting microstructural features such as grain size and shape as well as crystallographic textures are linked to mechanical properties such as strength, ductility and anisotropic elasticity and general rules for their evolution are defined. Residual stress distributions are detailed and discussed with regard to the causing geometrical and forming process related aspects. The aim of this paper is to give a comprehensive overview of the properties of profiles produced by linear flow splitting and linear bend splitting and to illustrate general rules for their evolution in order to provide guidelines for an optimized product development process which allows a beneficial use of the manufacturing‐induced properties.
