Complex structural components made from 7xxx series alloys are usually manufactured
through hot stamping due to their low ductility at room temperature. With the help of a custom …

We focus on the importance of accurately describing the flow behaviors of metallic materials
to be cold formed; we refer to several valuable examples. We review the typical …

Magnesium sheet metal alloys have a hexagonal close packed (hcp) crystal structure that
leads to severe evolving anisotropy and tension-compression asymmetry as a result of the …

To accurately model warm and hot forming operations, correct values for heat transfer
coefficient (HTC) are required, among other parameters. In this work, an experimental …

Forming 7000-series aluminum alloys under elevated temperatures is particularly attractive
due to their increased formability. To enable process design by finite element simulation for …

Mobilität stellt die Voraussetzung für die wirtschaftliche und soziale Entwicklung unserer
modernen Dienstleistungs-und Industriegesellschaft dar. Damit Mobilität auch in Zukunft …

The traditional flow models with an emphasis on Voce family flow models are criticized using
a typical monotonic strain-hardening material and a double strain-hardening (DSH) material …

This thesis investigates warm forming of 6000 and 7000 series aluminum alloys, namely
AA6013 T6, AA7075 T6 and a developmental 7000 series alloy (designated AA70XX T76) …

Traditionally, simple flow stress laws including Hollomon and Swift models have been much
employed. However, the simple models or laws could cover only limited part of materials …

This work examines the nature of the strain distributions and limit stains during die
quenching of a 7000-series aluminum alloy sheet. Forming limit experiments using limiting …
