Effect of Carbon in Severe Plastically Deformed Metals
Andrea Bachmaier, Reinhard Pippan, Oliver Renk
In the last decades severe plastic deformation techniques have gained increasing interest as they allow the production of bulk nanostructured materials with superior mechanical and…
On the reinforcement homogenization in CNT/metal matrix composites during severe plastic deformation
Katherine Aristizabal, Andreas Katzensteiner, Andrea Bachmaier +2
Carbon nanotube (CNT)-reinforced nickel matrix composites with different concentrations were processed by high pressure torsion (HPT). We thoroughly characterized the CNT agglomera…
Influence of Processing Parameters on the Mechanical Properties of HPT-Deformed Nickel Carbon Nanotube Composites
Andreas Katzensteiner, Timo Mueller, Karoline Kormout +4
Nickel carbon nanotube composites with varying amounts of carbon nanotubes are deformed by high pressure torsion at different deformation temperatures to high strains, where no fur…
Study of the structural defects on carbon nanotubes in metal matrix composites processed by severe plastic deformation
Katherine Aristizabal, Andreas Katzensteiner, Andrea Bachmaier +2
Carbon nanotubes (CNT) have been recently proposed as stabilizers against grain growth that can happen even at low temperature inputs in nano-crystalline and ultrafine-grained mate…
High-Pressure Torsion Deformation Induced Phase Transformations and Formations: New Material Combinations and Advanced Properties
Andrea Bachmaier, Reinhard Pippan
Heavy plastic shear deformation at relatively low homologous temperatures is called high-pressure torsion (HPT) deformation, which is one method of severe plastic deformation (SPD)…
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

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…
Impact of interfaces on the radiation response and underlying defect recovery mechanisms in nanostructured Cu-Fe-Ag
Michael Wurmshuber, David Frazer, Andrea Bachmaier +3
Newest developments in nuclear fission and fusion technology as well as planned long-distance space missions demand novel materials to withstand harsh, irradiative environments. Ra…
