El programari lliure ha deixat de ser domini exclusiu dels experts en informàtica. La majoria dels usuaris d’Internet coneixen el navegador web Firefox o el paquet ofimàtic OpenOffice.org, i molts els fan servir cada dia. Però en el sector de les tecnologies de la informació i la comunicació ja fa molts anys que es fan servir programes lliures per...
Article
The nanocrystallization process, promoted in an amorphous alloy with nominal composition Al89Nd7Ni4 by annealing (~10 min) at temperatures between 480 and 530 K (primary crystallization interval), results in the development of a distribution of primary nanocrystalline particles, with sizes below 10 nm. In the initial steps the nanocrystallization p...
Article
Al87Ni7Cu3Nd3 ribbons, prepared by melt-spinning, have been analysed by differential scanning calorimetry, and their nanostructural evolution has been studied by combining heat treatments with conventional X-ray diffraction, high-temperature X-ray diffraction, high resolution transmission electron microscopy and selected area electron diffraction....
Article
Rapidly solidified Al87Ni7Cu3Nd3 metallic glasses, prepared by using melt spinning, were treated under both isothermal and non-isothermal regime. The amorphous ribbon and the annealed samples were examined by means of differential scanning calorimetry, X-ray diffraction and high resolution transmission electron microscopy with selected-area electro...
Article
In the present study, rapidly solidified ribbons of Al87Ni7Cu3 Nd3 metallic glass was prepared by using melt spinning. Devitrification process of the totally amorphous ribbons was investigated by high temperature X-ray diffraction analysis, combining with differential scanning calorimetry, under continuous and isothermal heating regime. The X-ray d...
Article
Rapidly solidified Al87Ni7Cu3Nd3 metallic glasses were prepared by using melt spinning. Its calorimetric behavior was characterized by using differential scanning calorimeter. The metallic glasses were partially crystallized under continuous heating regime. Primary crystallization was studied through structural characterization of the amorphous and...
Article
The kinetics of transformation of the melt spun Al87Ni7Nd3Cu3 alloy was analysed by differential scanning calorimetry (DSC) and neutron diffraction (ND) experiments. The study of the emerging nanocrystalline grained structure by in situ heat treatment on quenched ribbons of the aluminium rich alloy composition indicates that no detectable nanocryst...

The decision to publish educational materials openly and under free licenses brings up the challenge of doing it in a sustainable way. Some lessons can be learned from the business models for production, maintenance and distribution of Free and Open Source Software. The Free Technology Academy (FTA) has taken on these challenges and has implemented...
