“…In practice, the limitations on size have been addressed in several investigations, which have confirmed the feasibility of scaling the ECAP process to billets having large cross-sections. [23][24][25] Processing by HPT is different because it is a continuous operation that can be adapted easily for different processing routes using strain reversals during the torsional straining. [26][27][28][29][30] Nevertheless, the applications of the process are restricted because it generally uses thin disk samples.…”

“…ECAE process has been successfully used to produce a variety of ultra-fined grained or nanostructured materials [6][7][8]. Among them, aluminium and aluminium alloys are studied most thoroughly due to their high ductility and ease of processing [7][8][9][10].…”

“…A lot of work had been performed on Al-6061 alloy to study the improvement in properties due to the effects of the number of ECAE passes [5,[10][11][12][13] and ECAE processing at room temperature [1,[14][15][16][17]. However, detailed studies on the effects of Al-6061 alloy due to different pre-extrusion heat treatments after multi passes of ECAE processing at room temperature using a 90 • die angle have not been reported.…”

ResumenEn el presente trabajo se ha realizado un estudio de la modificación de las propiedades mecánicas de la aleación de aluminio AA6060 F, al ser deformada mediante deformación plástica severa empleando el proceso de extrusión en canal angular (ECAE). Asimismo, se ha efectuado un estudio del efecto del envejecimiento artificial sobre la modificación de dichas propiedades mecánicas. Para ello, se han realizado tratamientos térmicos a diferentes temperaturas y tiempos de permanencia, efectuando mediciones de dureza, ensayos de tracción, ensayos con péndulo Charpy y técnicas de revelado metalográfico, para conocer los comportamientos mecánicos y el estado del material. Existe un elevado número de publicaciones, que han analizado el efecto de tratamientos térmicos de envejecimiento en aleaciones de la serie 6000. Sin embargo, la aleación AA6060 no ha sido tan ampliamente estudiada. Por ello, en este trabajo se parte de una aleación comercial AA6060 en estado de bruto de colada, lo cual no ha sido estudiado hasta la fecha. Palabras claveECAE; SPD; Envejecimiento; Aluminio; UFG. Analysis of the influence of aging heat treatment on the modification of the mechanical properties of the alloy AA6060 processed by ECAE AbstractIn the present work, a study on the modification of the mechanical properties of the aluminium alloy AA6060 F has been made when severe plastic deformation is applied to it through Equal Channel Angular Extrusion (ECAE). Moreover, a study about the effect of the artificial aging on the modification of such mechanical properties has been carried out after having processed the material by ECAE. In order to do this, thermal treatments at different values of temperature and holding time have been performed. Hardness, tensile tests and Charpy impact test, along with metallographic techniques, have been carried out in order to analyse the mechanical behaviour and the state of the material. In spite of the existence of several studies that have analysed the effect of aging thermal treatments on 6000 aluminium alloys, such studies are focused on laboratory alloys with industrial compositions not very usual. Therefore, in the present work, the employed starting material is a commercial alloy as-cast, which has not been studied up to now.
