The role played by the microstructures ensuing from phase transformations on the mechanical properties is now very well documented and thoroughly studied, in particular in metallic alloys. Although there is also a large number of works devoted to the reverse, i.e. the influence of mechanics on the ... [more]

Application of Scientific Principles to Aluminium Automotive Sheet

Start: Nov 6, 2017 11:00 AM c.t. (Local Time Germany)
End: Nov 18, 2017 11:45 AM
Speaker: Prof. Robert E. Sanders, Jr.
Chongqing University Senior Technical Advisor, Novelis Global Research and Technology Center

Host: Prof. Dierk Raabe / Dr. Dirk Ponge

Abstract Aluminium has been used in the manufacture of automobiles for more than 100 years and current usage averages more than 150kg per vehicle. Recent demands for higher fuel economy, improved vehicle performance, and lower CO₂ emissions are currently driving a dramatic increase in the usage of ... [more]

Shear bands in metallic glasses: what are they, how to find them?

Date: Oct 25, 2017
Time: 10:00 AM c.t. - 11:00 AM (Local Time Germany)
Speaker: P. Denis
University of Ulm, Institute of Micro and Nanomaterials, Albert-Einstein-Allee 47, D-89081 Ulm, Germany pierre.denis@uni-ulm.de
Location: Max-Planck-Institut für Eisenforschung GmbH
Room: Seminar Room 1

The plastic deformation in metallic glasses proceeds through the activation and sliding of shear bands (SBs). A better plasticity in metallic glasses can be achieved through the enhancement of SB stability and proliferation. Therefore, efforts have been made to understand the true nature of SBs in ...

Results in modeling complex polycrystalline structures by phase-field models that monitor the local crystallographic by scalar or vector orientation fields will be reviewed. The applied models incorporate homogeneous and heterogeneous nucleation of growth centers, and several mechanisms to form new ... [more]
