Journal ArticleDOI
The influences of temperature and microstructure on the tensile properties of a CoCrFeMnNi high-entropy alloy
F. Otto,F. Otto,Antonín Dlouhý,Christoph Somsen,Hongbin Bei,Gunther Eggeler,Easo P. George,Easo P. George +7 more
TL;DR: In this article, an equiatomic CoCrFeMnNi high-entropy alloy, which crystallizes in the face-centered cubic (fcc) crystal structure, was produced by arc melting and drop casting.
Journal ArticleDOI
Amorphous Cobalt Boride (Co2B) as a Highly Efficient Nonprecious Catalyst for Electrochemical Water Splitting: Oxygen and Hydrogen Evolution
Justus Masa,Philipp Weide,Daniel Peeters,Ilya Sinev,Wei Xia,Zhenyu Sun,Christoph Somsen,Martin Muhler,Wolfgang Schuhmann +8 more
TL;DR: In this article, it is demonstrated that amorphous cobalt boride (Co2B) prepared by the chemical reduction of CoCl2 using NaBH4 is an exceptionally efficient electrocatalyst for the oxygen evolution reaction (OER) in alkaline electrolytes and is simultaneously active for catalyzing the hydrogen evolution reaction.
Journal ArticleDOI
On the multiplication of dislocations during martensitic transformations in NiTi shape memory alloys
TL;DR: In this article, the authors used in situ and post-mortem diffraction contrast transmission electron microscopy (TEM) to study the multiplication of dislocations during a thermal martensitic forward and reverse transformation in a NiTi shape memory alloy single crystal.
Journal ArticleDOI
Advanced Scale Bridging Microstructure Analysis of Single Crystal Ni-Base Superalloys†
A.B. Parsa,P. Wollgramm,H. Buck,Christoph Somsen,Aleksander Kostka,Ivan Povstugar,Pyuck-Pa Choi,Dierk Raabe,Antonín Dlouhý,Julian George Müller,Erdmann Spiecker,Kathrin Demtröder,Jürgen Schreuer,Klaus Neuking,Gunther Eggeler +14 more
TL;DR: In this paper, the authors show how conventional and advanced mechanical, chemical, and microstructural methods can be used to characterize cast single crystal Ni-base superalloy (SX) plates across multiple length scales.
Journal ArticleDOI
High-temperature and low-stress creep anisotropy of single-crystal superalloys
L. Agudo Jácome,P. Nörtershäuser,J.-K. Heyer,A. Lahni,Jan Frenzel,A. Dlouhy,Christoph Somsen,Gunther Eggeler +7 more
TL;DR: The high-temperature and low-stress creep of the Ni-based superalloy LEK 94 is investigated in this article, comparing the tensile creep behavior of miniature creep specimens in [0, 0, 1] and [1, 1, 0] directions.
