Análisis de perfiles de difracción de rayos X de una aleación Cu-8% en peso de Cr obtenida por medio de aleado mecánico

This work studies the evolution of the microstrucutre of a mechanically alloyed Cu-8 wt. % Cr powder mixture by X-Ray profiles analysis. The process was carried out using a SPEX8000D upon mix with stainless steels containers and balls, keeping a constant powder to balls weight ratio of 10. Increasing the milling time, crystallite size and stacking fault energy decreased and microstrain and stacking fault probability increased. The crystallite size distribution shifts to lower crystallite size values by increasing the milling time. After a milling time of 50 hours, the data showed that a solid solution of chromium in copper was produced.
