Thermodynamic instability of a nanocrystalline, single-phase TiZrNbHfTa alloy and its impact on the mechanical properties
(2018)
An equiatomic, single-phase TiZrNbHfTa high-entropy alloy was subjected to high-pressure torsion, leading to a grain size below 100 nm. Introducing a nanocrystalline microstructure to the material should help to accelerate ...
Rogue waves in the southern North Sea : Extremwellen in der südlichen Nordsee
(2022)
Rogue waves are exceptionally high waves, relative to the surrounding sea state. They occur rarely, which makes them difficult to predict. Due to their particular height and limited predictability, they pose a threat to ...
The isothermal evolution of nanoporous gold from the ring perspective - an application of graph theory
(2020)
The ring structures of five isothermally annealed nanoporous gold (npg) samples were analyzed explicitly by applying results and algorithms from graph theory to skeletonized 3D reconstructions from focused ion beam (FIB) ...
Contributions from Changing Large-Scale Atmospheric Conditions to Changes in Scandinavian Temperature and Precipitation Between Two Climate Normals
(2022)
Multidecadal changes in regional climate can occur as a forced response to changing greenhouse gases and aerosols, as a result of natural internal climate variability, or due to their combination. Internal climate variability ...
Skilful prediction of cod stocks in the North and Barents Sea a decade in advance
(2021)
Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ...
Experimental study on incremental sheet forming of magnesium alloy AZ31 with hot air heating
(2018)
Products of tomorrow are characterized by environmental sustainability, individuality and economic feasibility. This trend also occurs in the field of sheet metal forming. Lightweight materials such as magnesium alloys are ...
Skillful decadal prediction of German Bight storm activity
(2022)
We evaluate the prediction skill of the Max Planck Institute Earth System Model (MPI-ESM) decadal hindcast system for German Bight storm activity (GBSA) on a multiannual to decadal scale. We define GBSA every year via the ...
Thixomolded AZ91D and MRI153M magnesium alloys and their enhanced corrosion resistance
(2020)
AZ91D and MRI153M alloys were produced by thixomolding. Their corrosion resistance is significantly higher than that of similar materials produced by ingot or die‐casting. A corrosion rate smaller than 0.2 mm/year in 5 wt% ...
Tidal mitigation of offshore wind wake effects in coastal seas
(2022)
With increasing offshore wind development, more and more marine environments are confronted with the effects of atmospheric wind farm wakes on hydrodynamic processes. Recent studies have highlighted the impact of the wind ...
