Microstructure and properties of hard layers formed by duplex surface treatment containing nickel and phosphorus on a titanium-base alloy

Microstructure and chemical composition of the hard Ni–P–Ti layer formed on the Ti–6Al–4V alloy after duplex surface treatment were investigated by light microscopy, X-ray diffraction, scanning electron microscopy and analytical/high resolution transmissio ...

Transmission electron microscopy and atomic force microscopy characterisation of titanium-base alloys nitrided under glow discharge

Philippe Buffat

The microstructure of titanium alloys (Ti–1Al–1Mn, Ti–6Al–4V) nitrided under glow discharge was characterised using light microscopy, X-ray diffraction and analytical electron microscopy. The investigations revealed a complex multilayered microstructure pr ...

The influence of Ti doping methods on the high field performance of (Nb, Ta, Ti)3Sn multifilamentary wires using Osprey bronze

Philippe Buffat, Marco Cantoni, Davide Uglietti

We have analyzed the influence of the two different Ti doping methods on the superconducting properties of bronze processed (Nb,Ta,Ti)3Sn multifilamentary wires with identical configuration, consisting of a Nb7.5wt.%Ta alloy processed to 14641 filaments of ...

Titanium oxides and silicates as high-kappa dielectrics: A first-principles investigation

Alfredo Pasquarello

Using density functional theory, we investigate the structural, vibrational, and dielectric properties of titanium oxides and silicates, which have attracted considerable attention in the framework of the quest for alternative high-K materials. For the oxi ...

Calcium phosphate drug delivery system: influence of local zoledronate release on bone implant osteointegration

Dominique Pioletti, Bastian Peter

Despite total hip replacement (THR) gives generally satisfactory results, the quality of outcome in young patients is markedly decreased compared to the average THR outcome. For this population, pharmacological treatment with bisphosphonate would be benefi ...

On the strain-hardening of tempered martensitic alloys

Philippe Spätig, Raul Alejandro Bonadé

The strain-hardening behaviour of a tempered martensitic iron-chromium-carbon model was examined in terms of dislocation mechanics. Tensile tests of this body-centered cubic alloy were carried out from 77 up to 293 K. A specific relationship between the fl ...

Temperature dependence of irradiation effects in pure titanium

Nadine Baluc

The microstructural modifications due to irradiation in hcp pure metals and their consequences on the mechanical properties have been investigated. Experimental results for proton-irradiated pure polycrystalline titanium are presented and discussed. Sample ...

High-strain response of piezoresistive thick-film resistors on titanium alloy substrates

Peter Ryser, Thomas Maeder, Caroline Jacq

We examine, in this work, the integration and high-strain response of piezoresistive thick-film resistors on titanium and titanium alloy, as compared with ferritic stainless steel and the standard alumina substrates. In general, titanium and its alloys are ...

Plastic flow of martensitic model alloys

Philippe Spätig, Robin Schäublin, Raul Alejandro Bonadé

Modeling of the constitutive behavior was undertaken for Fe- Cr-C tempered martensitic alloys. Tensile tests were carried out at room temperature and constant nominal strain rate. In order to obtain a fully martensitic structure with different prior austen ...

Immediate implant placement using injectable calcium phosphate hydraulic cement in dogs

Jacques Lemaître, Pascale Van Landuyt

Techniques allowing implant placement in extraction sockets require either high diameter implants in surgically enlarged sockets or grafting and/or regenerative procedures around implants after their primary surgical stabilization. This study aimed to eval ...
