| Abstract Scope |
During the manufacturing of semi-finished products the material is subjected to various forming steps. It is annealed before component manufacturing in order to reduce hardening and to ensure a good formability. Inhomogeneous pre-strengthening of the material influences the stress distribution during full forward extrusion. This affects the part’s residual stress state and therefore its operating and failure behaviour. For prediction of the residual stress state, influences of the material delivery condition must be known. The aim of this paper is to derive dependencies between material properties and resulting residual stresses in the component. For this purpose, stainless steel in different delivery conditions is used. Residual stresses, microstructure and microhardness distribution of the materials are compared regarding the rods and extruded parts. The influences of the delivery condition are evaluated by comparing process and component properties. |
