Characterization in the icosahedral phase of the system Al63Cu25Fe12

Descripción del Articulo

The present work aimed to characterize the microstructure of the icosahedral phase (ɸ-quasicrystalline phase) of the system with stoichiometric composition of the quasicrystal Al63Cu25Fe12. The ternary alloy with nominal composition of Al63Cu25Fe12 was processed by Mechanical Alloying (MA) as a viab...

The ternary alloy with nominal composition of Al63Cu25Fe12 was processed by Mechanical Alloying (MA) as a viable solid state processing method for producing various metastable and stable quasicrystalline phases. The structural characterization of the obtained samples was performed by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), while the elemental composition of the chemical elements Al, Fe and Cu were determined by the technique of X-ray spectroscopy by dispersive energy (EDS). According to the results of XRD, the diffraction patterns of Al63Cu25Fe12 showed the presence of β-Al (Fe, Cu) and λ-Al13Fe4 phases coexist with the thermodynamic ɸ-phase quasicrystalline. Finally, elemental analysis indicates that during alloy synthesis there is little variation of the ideal composition. The results indicate that alloys with high percentage of icosahedral phase can be obtained by casting in the air.El presente trabajo tuvo como objetivo caracterizar la microestructura de la fase icosaédrica (fase ɸ-cuasicristalina) del sistema con composición estequiométrica del cuasicristal Al63Cu25Fe12. La aleación ternaria con composición nominal de Al63Cu25Fe12 se procesó mediante Aleación Mecánica (MA) como un método de procesamiento de estado sólido viable para producir varias fases cuasicristalinas metaestables y estables. La caracterización estructural de las muestras obtenidas se realizó mediante difracción de rayos X (XRD) y Microscopía Electrónica de Barrido (SEM), mientras que la composición elemental de los elementos químicos Al, Fe y Cu se determinó mediante la técnica de espectroscopía de rayos X por dispersión energía (EDS). Según los resultados de XRD, los patrones de difracción de Al63Cu25Fe12 mostraron la presencia de fases β-Al (Fe, Cu) y λ-Al13Fe4 que coexisten con la fase ɸ termodinámica cuasicristalina. Finalmente, el análisis elemental indica que durante la síntesis de la aleación hay poca variación de la composición ideal. Los resultados indican que se pueden obtener aleaciones con alto porcentaje de fase icosaédrica mediante colada al aire.Universidad Nacional Mayor de San Marcos2021-12-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/1561710.15381/rif.v24i3.15617Revista de Investigación de Física; Vol. 24 Núm. 3 (2021); 1-5Revista de Investigación de Física; Vol. 24 No. 3 (2021); 1-51728-29771605-7724reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/15617/17351Derechos de autor 2021 Luciano Nascimento, Anastasia Melnykhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:revistasinvestigacion.unmsm.edu.pe:article/156172021-12-30T12:21:12Z
