| Abstract (English): | The structural and microstructural characterization by means of X-ray diffraction (XRD) of the aluminum-titanium alloys (AlxTi3-x, 0.5 ≤ x ≤ 0:20) is presented. The analysis showed the occurrence of an order-disorder phase transition in the studied compositional range. The presence of a minor fcc phase within the hcp matrix of the AlxTi3-xalloy showed evidence of the presence of stacking faults. The probability of occurrence of this type of defect depends on the chemical composition and on the distance between atomic layers (order parameter). The microstructural analysis using the Warren-Averbach and Williamson-Hall methods shows that a decrease of Al content not only decreases the probability of occurrence of planar defects but also leads to a decrease in the average crystallite size and to an increase of the average non uniform microstrain value in the alloy. Deformation defects (α) predominate in this type of alloy. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Se presentala caracterización estructural y microestructural de aleaciones de aluminio - titanio (AlxTi3-x, 0.5 ≤ x ≤ 0.20) por medio de la técnica de difracción de rayos-X (DRX). El análisis mostró la ocurrencia de una transición de fase orden - desorden en el rango de composición estudiado. La presencia de una fase minoritaria fcc en la matriz hcp de la aleación AlTi3 mostró evidencia de la presencia de defectos de apilado, cuya probabilidad de ocurrencia depende de la composición química y la distancia entre capas atómicas (parámetro de orden). El análisis microestructural usando los métodos de Warren-Averbach y Williamson-Hall mostró que unadisminución del contenido de Al, no solo disminuye la probabilidad de ocurrencia de defectos planares sino que propicia una disminución del tamaño promedio de cristalitas y aun aumento del valor medio de la microdeformación no uniforme en la aleación. Los defectos de deformación (α) predominan en este tipo de aleación. [ABSTRACT FROM AUTHOR] |
