7th International Symposium on Computational Mechanics of Polycrystals, CMCn 2020 and DAMASK User Meeting

CMCn2020 The Max-Planck-Institut für Eisenforschung in Düsseldorf is organizing the 7th International Symposium on Computational Mechanics of Polycrystals and we would like to invite you and your research colleagues to participate in this event. This symposium is part of a biannual series of symposia that originated with the establishment of the first joint research group formed between the Max Planck Society and the Fraunhofer Society and investigating Computational Mechanics of Polycrystals. This year the symposium is again combined with the DAMASK User Meeting. DAMASK is the multi-physics simulation software developed at MPIE. The symposium will take place on September 14th and 15th, 2020 in the Max-Planck-Institut für Eisenforschung at Max-Planck-Straße 1, 40237 Düsseldorf, Germany.The DAMASK User Meeting will be held on the following two days, September 16th and 17th at the same location.

BiGmax Workshop 2020 on Big-Data-Driven Materials Science “CANCELLED”

We would like to communicate that the BiGmax ML/AI workshop IS CANCELLED! The reason for this decision is the currently on-going and not rationally and substantially predictable situation caused by the global Corona/Covid-19 pandemic.

Sustainable Metallurgy

Metallic materials which have enabled progress over thousands of years and are produced in huge quantities (e.g. 1.8 billion tons of steels per year), are now facing severe and in part abrupt limits set by sustainability constraints and the associated legislative measures. Accelerated demand for structural alloys in key areas such as energy, construction, infrastructure, safety, mobile communication and transportation creates growth rates of up to 200% until 2050. Yet, most of these materials are energy, greenhouse gas and pollution intense when extracted, produced and manufactured. The lecture provides an introduction to this field and reviews approaches to improve the sustainability of and through structural metallic alloys. It reports about progress in direct sustainability for different steps along the value chain including CO2-reduced primary production; recycling; scrap-compatible alloy design; contaminant tolerance of alloys; and improved alloy longevity through corrosion protection, damage tolerance and repairability for longer product use. It is also shown how structural materials enable improved energy efficiency through reduced weight, higher thermal stability, and better mechanical properties. The respective leverage effects of the individual measures on rendering structural alloys more sustainable are described. [more]

Non-monotonic rheology of a magnetic liquid crystal system in an external fieldNon-monotonic rheology of a magnetic liquid crystal system in an external field

Utilizing molecular dynamics simulations, we report a non-monotonic dependence of the shear stress on the strength of an external magnetic eld (H) in a liquid-crystalline mixture of magnetic and non-magnetic anisotropic particles.This non-monotonic behavior is in sharp contrast with the well-studied monotonic H-dependency of the shear stress in conventional ferro uids, where the shear stress increases with H until it reaches a saturation value. We relatethe origin of this non-monotonicity to the competing eects of particle alignment along the shear-induced direction, on the one hand, and the magnetic eld direction on the other hand. To isolate the role of these competing eects,we consider a two-component mixture composed of particles with eectively identical steric interactions, where the orientations of a small fraction, i.e. the magnetic ones, are coupled to the external magnetic eld. By increasing Hfrom zero, the orientations of the magnetic particles show a Freederickz-like transition and eventually start deviating from the shear-induced orientation, leading to an increase in shear stress. Upon further increase of H, a demixingof the magnetic particles, from the non-magnetic ones, occurs which leads to a drop in shear stress, hence creating a non-monotonic response to H. Unlike the equilibrium demixing phenomena reported in previous studies, the demixingobserved here is neither due to size-polydispersity nor due to a wall-induced nematic transition. Based on a simplied Onsager analysis, we rather argue that it occurs solely due to packing entropy of particles with dierent shear- or magnetic-eld-induced orientations. [more]

5th NRW-APT User Meeting

The Max-Planck-Institut für Eisenforschung GmbH in Düsseldorf is organizing the 5th NRW-APT user meeting on November the 07th 2019 and we would like to invite you and your research colleagues to participate in this event. This meeting will bring together scientists from North Rhine-Westphalia dealing with APT technique or correlating APT with other techniques. We want to discuss problems and share knowledge regarding sample preparation, measurement conditions, data reconstruction & analysis, etc..If you and your colleagues would like to attend this event, then please register before October 18th 2019. There are limited places only. We are looking forward to see you in Düsseldorf! [more]
