Five ternary Sn-0.7Cu-xNi alloys with nickel contents in the range 0-1000 ppm have been directionally solidified at different growth rates. The competition between primary tetragonal Sn cells/dendrites, eutectic and primary Cu6Sn5 is interpreted with phase ...
This work is motivated by an industrial interest in gaining a better understanding of the phase transformations that govern the mechanical properties of 18-carat gold alloys commonly used in jewelry applications and luxury watchmaking. These alloys fall in ...
Tunnel transport processes are considered in a square lattice of metallic nanogranules embedded into insulating host to model tunnel conduction in real metal/insulator granular layers. Based on a simple model with three possible charging states (+/- or 0) ...
An alternative route to plasmon-controlled fluorescence for improving the detection of fluorescence is proposed. In place of a metallic layer, a suitable silicon-based one-dimensional photonic crystal is used to generate a Bloch surface waves-coupled emiss ...
In the current research, pressureless melt infiltration (PM!) was applied to study the effect of different processing conditions on the final properties of Al/SiC composites, fabricated through the infiltration of aluminum melt into SiC particulates porous ...
The ITER Toroidal Field (TF) conductor qualification phase has been carried out by testing short sample prototype conductors in the SULTAN test facility. This phase, started in 2007, has been substantially completed after minor adjustment of the conductor ...
Despite significant advances in computational materials science, a quantitative, parameter-free prediction of the mechanical properties of alloys has been difficult to achieve from first principles. Here, we present a new analytic theory that, with input f ...
Cu-Ni-Sn alloys with Pb additions exhibit high mechanical strength at room temperature coupled with good machinability but experience a significant ductility loss above the melting point of lead. We explore here the influence of minor additions of Al, Mn, ...
In organic conductors the overlap integral between layers is small In-plane momentum scattering is rapid and transport perpendicular to the layers is expected to be blocked We present a high frequency conduction electron spin resonance (CESR) study in the ...
This thesis is an exploration of deformation and fracture properties of a novel two-phase α2 + γ Ti46Al8Ta (at.%) alloy featuring a "convoluted" microstructure, produced by partners within a European Union project named IMPRESS. Properties of this alloy ar ...
