Abstract
espanolLos lingotes de CuTaAlSe3 y CuTaGaSe3 se sintetizaron usando la tecnica de fusion y recocido. Se usaron tecnicas de difraccion de Rayos X (DRX) y Analisis Termico Diferencial (ATD) para la caracterizacion de las aleaciones. El analisis del patron de difraccion indica que ambas muestras estan compuestas por dos fases: la fase promedio indexada como una estructura hexagonal y la fase secundaria indexada como una estructura tetragonal de tipo calcopirita. De la forma de los picos del ATD para las aleaciones CuTaAlSe3 y CuTaGaSe3 se deduce que la fusion es incongruente para ambos materiales de valor ~ 1348K y ~ 1235K, respectivamente. Palabras clave: EnglishThe ingots of CuTaAlSe3 and CuTaGaSe3 were synthesized using the melt and annealing technique. X-Ray Diffraction (XRD) and Differential Thermal Analysis (DTA) techniques were used for characterization of the alloy. The analysis of the diffraction pattern indicates that both samples are composed of two phases; the mean phase indexes as a hexagonal structure, whereas the second phase indexes as a tetragonal chalcopyrite-like structure. From the shape of the DTA peaks for the CuTaAlSe3 and CuTaGaSe3 alloys, was deduced that the melting is incongruent for both materials, the value of ~1348K and ~1235K, respectively.
采用熔融退火技术合成了CuTaAlSe3和CuTaGaSe3锭。采用X射线衍射(xrd)和差热分析(dta)技术对合金进行了表征。衍射模式分析表明,两种样品均由两种相组成:以六角形结构为指标的平均相和以四方黄铜矿结构为指标的二次相。从CuTaAlSe3和CuTaGaSe3合金的ATD峰的形状可以看出,这两种材料的熔合值分别为~ 1348K和~ 1235K。CuTaAlSe3和CuTaGaSe3的ingots是用熔融退火技术合成的。采用x射线衍射(XRD)和差热分析(DTA)技术对合金进行了表征。对衍射模式的分析表明,两种样品均由两相组成;= =地理= =根据美国人口普查,这个县的面积为。From the shape of the DTA peaks for the CuTaAlSe3 and was CuTaGaSe3合金,deduced that the melting is incongruent for both materials, the value of ~ 1348K and ~ 1235K, respectively。
