          Abstract

          El objetivo del presente estudio fue determinar la relación entre las transformaciones de fases ocurridas durante la soldadura por fricción radial de una aleación de aluminio AA 5754 de 12 mm de diámetro. El proceso se realizó en un torno 16 K 20 considerando para la unión parámetros de 1 200 y 1 400 rev/min con una presión de 0,9 y 1,9 MPa respectivamente. Se determinó que la temperatura de fricción disminuye en la medida que se incrementa el número de revoluciones, así como la variación metalúrgica tanto en la zona afectada termo-mecánicamente, como en la afectada térmicamente. Los perfiles de dureza demuestran el incremento por el efecto del flujo plástico, las variaciones metalúrgicas y la presencia de precipitados.

          The objective of this investigation is to determine the relation between the transformations of phases occurring during the rotational friction welding of AA 5754 12-mm-diameter aluminum alloys. The process was carried out using a 16 K 20 lathe based on joint parameters ranging between 1 200 and 1 400 rev/min with a pressure of 0,9 and 1,9 MPa, respectively. It was determined that the friction temperature decreases as the number of revolutions increases as well as the metallurgical variation both in the thermo-mechanically affected area and in the thermally affected area. The hardness profiles show the increase by the plastic flow effect, metallurgical variations and the existence of precipitates.
