| Abstract |
Within subproject A2 processes leading to local Bake Hardening (BH) effects in
multiphase steels will be investigated. The characteristic values which integrally describe the Bake
Hardening effect depend on the deformation path and the degree of preforming, as well as on
temperature and duration of the subsequent heat treatment. The thermal stability of the induced
strengthening is also determined, in order to specify the boundary conditions for thermal
assembling. Thus, they can be qualified for the assembly of locally strengthened structural
components. |
