Modeling the amorphous structure of a mechanically alloyed Ti50Ni25Cu25 alloy using anomalous wide-angle x-ray scattering and reverse Monte Carlo simulations
João Cardoso de Lima, Claudio Michel Poffo, Sergio Michielon de Souza +4
An amorphous Ti50Ni25Cu25 alloy was produced by 19 h of mechanical alloying. Anomalous wide angle x-ray scattering data were collected at six energies and six total scattering fact…
Structural and optical studies of FeSb2 under high pressure
Claudio Michel Poffo, Sergio Michielon de Souza, Daniela Menegon Trichês +4
Nanostructured orthorhombic FeSb2 and an amorphous phase were formed by mechanical alloying starting from a mixture of high purity elemental Fe and Sb powders. The effects of high…
New pressure-induced monoclinic β-Sb2Te3 phase with sevenfold symmetry
Sergio Michielon de Souza, Daniela Menegon Trichês, Claudio Michel Poffo +4
A nanometric Sb2Te3 rhombohedral phase was produced from Sb and Te by mechanical alloying for 3 hours and its structural stability was studied by synchrotron X-ray diffraction (XRD…
Reverse Monte Carlo Simulations and Raman Scattering of an Amorphous GeSe Alloy Produced by Mechanical Alloying
K. D. Machado, J. C. de Lima, C. E. M. Campos +2
The short and intermediate range order of an amorphous GeSe alloy produced by Mechanical Alloying were studied by Reverse Monte Carlo simulations of its x-ray total structure f…
Magnetic properties of amorphous CoNb alloys produced by mechanical alloying
K. D. Machado, R. C. da Silva, J. C. de Lima +3
Three amorphous CoNb alloys, CoNb, CoNb and CoNb, were produced by Mechanical Alloying starting from the elemental powders.…
Comparison among the local atomic order of amorphous TM-Ti alloys (TM=Co, Ni, Cu) produced by Mechanical Alloying studied by EXAFS
K. D. Machado, J. C. de Lima, C. E. M. Campos +1
We have investigated the local atomic structure of amorphous TM-Ti alloys (TM = Co, Ni, Cu) produced by Mechanical Alloying by means of EXAFS analyses on TM and Ti K-edges. Coordin…
