Abstract
Cast high alloyed metastable austenitic CrMnNi-TRIP-steels are rather novel corrosion resistant materials and still under development. Due to the transformation-induced plasticity effect (TRIP) high stresses combined with high ductility can be achieved up to high strain rates of 10³ 1/s. Deformation temperatures and strain rate influence the martensitic phase transformation rate during plastic deformation and have a strong effect on achieved strength and failure properties. Despite the cast coarse grained microstructure, a high energy consumption up to crash relevant strain rates is reached due to the pronounced TRIP-effect.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
