A new approach to evaluate the elastic modulus of metallic foils
C. O. W. Trost, S. Wurster, C. Freitag +2
The accurate determination of the elastic properties is non-trivial for metallic foils. The measured elastic modulus is often described in literature as significantly smaller than…
Microstructural Changes Influencing the Magnetoresistive Behavior of Bulk Nanocrystalline Materials
Stefan Wurster, Martin Stueckler, Lukas Weissitsch +2
Bulk nanocrystalline materials of small and medium ferromagnetic content were produced using severe plastic deformation by high-pressure torsion at roomtemperature. Giant magnetore…
Intermixing of Fe and Cu on the atomic scale by high-pressure torsion as revealed by DC- and AC-SQUID susceptometry and atom probe tomography
Martin Stückler, Heinz Krenn, Philipp Kürnsteiner +6
The capability of high-pressure torsion on the preparation of supersaturated solid solutions, consisting of Cu-14Fe (wt.%), is studied. From microstructural investigations a steady…
Tuneable Magneto-Resistance by Severe Plastic Deformation
Stefan Wurster, Lukas Weissitsch, Martin Stueckler +4
Bulk metallic samples were synthesized from different binary powder mixtures consisting of elemental Cu, Co, and Fe using severe plastic deformation. Small particles of the ferroma…
Magnetic Binary Supersaturated Solid Solutions Processed by Severe Plastic Deformation
Martin Stückler, Heinz Krenn, Reinhard Pippan +3
Samples consisting of one ferromagnetic and one diamagnetic component which are immiscible at the thermodynamic equilibrium (Co-Cu, Fe-Cu, Fe-Ag) are processed by high-pressure tor…
Magnetic dilution by severe plastic deformation
Martin Stückler, Lukas Weissitsch, Stefan Wurster +4
Mixtures of Fe and Cu powders are cold-compacted and subsequently deformed with severe plastic deformation by high-pressure torsion, leading to bulk samples. The dilution of Fe in…
Fracture mechanics of micro samples: Fundamental considerations
Reinhard Pippan, Stefan Wurster, Daniel Kiener
In this review article we consider the crack growth resistance ofmicrometer and submicrometer sized samples from the fracture mechanics point of view. Standard fracture mechanics t…
An analytical solution for the correct determination of crack lengths via cantilever stiffness
Markus Alfreider, Stefan Kolitsch, Stefan Wurster +1
The present work provides an analytic solution for the stiffness to crack length relation in microscopic cantilever shaped fracture specimens based on classical beam theory and sub…
Microstructure and Failure Characteristics of Nanostructured Molybdenum Copper Composites
Katharina Schwarz, Julian Rosalie, Stefan Wurster +2
Liquid-metal infiltrated Cu30Mo70 (weigth percentage) is subjected to severe plastic deformation using high pressure torsion. The initially equiaxed dual phase structure is gradual…
