Influence of the grain size on the in vivo degradation behaviour of the magnesium alloy LAE442

Ullmann, Berit; Reifenrath, Janin; Seitz, Jan-Martin; Bormann, Dirk; Meyer-Lindenberg, Andrea (London : SAGE Publications Ltd., 2013)

The aim of this study was to investigate the differences in the in vivo degradation behaviour of magnesium implants with various grain sizes and damaged surfaces. For this purpose, three different LAE442 magnesium implants ...
Investigation on the microstructure of ecap-processed iron-aluminium alloys

Behrens, Bernd-Arno; Brunotte, Kai; Petersen, Tom; Relge, Roman (Basel : MDPI AG, 2021)

The present work deals with adjusting a fine-grained microstructure in iron-rich iron-aluminium alloys using the ECAP-process (Equal Channel Angular Pressing). Due to the limited formability of Fe-Al alloys with increased ...
A model test study on the parameters affecting the cyclic lateral response of monopile foundations for offshore wind turbines embedded in non-cohesive soils

Frick, Dennis; Achmus, Martin (Göttingen : Copernicus Publications, 2022)

During their service life, monopiles supporting offshore wind turbines are subjected to a large number of lateral cyclic loads resulting from complex environmental conditions such as wind and waves varying in amplitude, ...
Nanocrystalline versus microcrystalline Lo2O:B2O 3 composites: Anomalous ionic conductivities and percolation theory

Indris, Sylvio; Heitjans, Paul; Roman, H. Eduardo; Bunde, Armin (College Park, ML : American Physical Society, 2000)

We study ionic transport in nano- and microcrystalline (1−x)Li2O:xB2O3 composites using standard impedance spectroscopy. In the nanocrystalline samples (average grain size of about 20 nm), the ionic conductivity σdc increases ...
Numerical simulation of electromagnetic stirring in continuous casting of wires

Turewicz, P.; Baake, E.; Umbrashko, A. (Bingley : Emerald Group Publishing Ltd., 2011)

Purpose - The purpose of this paper is to describe how electromagnetic stirring during continuous casting of ferrous and non-ferrous metals is applied in order to increase the homogeneity and the material properties by ...
