Use of Bake Hardening Effects to Change Local Properties of Constructional Elements
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.
