AISI 304 and 316 stainless steels of two purity levels that have been irradiated with high energy protons up to 0.3 dpa and neutrons in a high flux reactor up to 7.5 dpa were investigated in terms of irradiation induced mechanical properties and microstruc ...
In situ cathodoluminescence experiments have been performed to follow the time dependence of the UV luminescence in epitaxial lateral overgrowth GaN specimens. The decrease of the observed intensity and red-shift of the UV peak are interpreted in terms of ...
The materials used for cutting tool applications are principally divided in two classes: the WC-Co cemented carbides, tough but with a limited resistance to deformation at high temperature, and the TiCN-Mo-Co cermets, more refractory but less tough than th ...
Predicting microstructure evolution of metals under irradiation requires an in depth understanding of the production and properties of point defects and their clusters. Although, analytical descriptions based on the production bias model have recently been ...
Segregation of P and Mo to prior austenite grain boundaries in a 2.25Cr1Mo steel subjected to neutron irradiation and ageing is examined using field emission gull scanning transmission electron microscopy (FEGSTEM) with energy dispersive X-ray microanalysi ...
We describe the first stage of the evolution of CL spectra, intensity and dislocation contrast under low keV electron beam for ELO-GaN with a low dislocation density. The UV and yellow intensities are decreased by beam irradiation. We have observed a broad ...
Nucleation and growth of Pd on cleaved MgO(001) surfaces were studied by variable-temperature atomic force microscopy in the temperature range 200-800 K. Constant island densities (similar to 3x10(12)cm(-2)) were observed over a wide temperature range, ind ...
Poly-quasicrystalline samples of an icosahedral Al-Cu-Fe alloy have been deformed in compression tests under constant-strain-rate conditions at temperatures ranging from room temperature up to 1020 K (m approximate to 1150 K, where T-m is the melting tempe ...
The interaction of vacancy loops (VLs) and stacking-fault tetrahedra (SFTs) with point defects and the processes of growth and shrinkage of VLs and SFTs have been studied using computer simulation and a long-range pair potential for copper. It was found th ...
Dislocation dynamics in a Ni-3(Al, Ta) single-crystal alloy have been studied by means of mechanical spectroscopy at intermediate temperatures, that is in the temperature range of the flow stress anomaly. The mechanical loss of specimens predeformed at 300 ...
