Journal ArticleDOI
Mechanical properties, microstructure and thermal stability of a nanocrystalline CoCrFeMnNi high-entropy alloy after severe plastic deformation
Benjamin Schuh,Francisca Mendez-Martin,Bernhard Völker,Easo P. George,Easo P. George,Helmut Clemens,Reinhard Pippan,Anton Hohenwarter +7 more
TL;DR: In this article, an equiatomic CoCrFeMnNi high-entropy alloy (HEA), produced by arc melting and drop casting, was subjected to severe plastic deformation (SPD) using high pressure torsion.
Journal ArticleDOI
Thermodynamic instability of a nanocrystalline, single-phase TiZrNbHfTa alloy and its impact on the mechanical properties
Benjamin Schuh,Bernhard Völker,Juraj Todt,Norbert Schell,Loïc Perrière,Jun Li,Jean-Philippe Couzinié,Anton Hohenwarter +7 more
TL;DR: In this article, an equiatomic, single-phase TiZrNbHfTa high-entropy alloy was subjected to high-pressure torsion, leading to a grain size below 100nm.
Journal ArticleDOI
Ultra-strong and damage tolerant metallic bulk materials: A lesson from nanostructured pearlitic steel wires.
Anton Hohenwarter,Bernhard Völker,Marlene Kapp,Yujiao Li,Shoji Goto,Shoji Goto,Dierk Raabe,Reinhard Pippan +7 more
TL;DR: This work uses today’s strongest metallic bulk material, namely, a nanostructured pearlitic steel wire, and measured the fracture toughness on micron-sized specimens in different crack growth directions and found an unexpected strong anisotropy in the fracture resistance.
Journal ArticleDOI
Influence of Annealing on Microstructure and Mechanical Properties of a Nanocrystalline CrCoNi Medium-Entropy Alloy
Benjamin Schuh,Bernhard Völker,Bernhard Völker,Bernhard Völker,Juraj Todt,K.S. Kormout,Norbert Schell,Anton Hohenwarter +7 more
TL;DR: An equiatomic CrCoNi medium-entropy alloy was subjected to high-pressure torsion, which led to a refinement of the microstructure to a grain size of about 50 nm, combined with a strong increase in the materials hardness.
Journal ArticleDOI
Microstructure and metallic ion release of pure titanium and Ti–13Nb–13Zr alloy processed by high pressure torsion
Ivana D. Dimić,Ivana Cvijović-Alagić,Bernhard Völker,Anton Hohenwarter,Reinhard Pippan,Đorđe Veljović,Marko Rakin,Branko Bugarski +7 more
TL;DR: In this paper, a study was conducted to determine metallic ion release from commercially pure titanium (CPTi) and Ti-13Nb-13Zr alloy processed by high pressure torsion (HPT).
