“…The aluminum alloy Al-Zn-Mg-Cu 7075 is used in various auto body and aerospace applications because of its high specific strength, low quench sensitivity, wide range of solution heat treatment temperatures and rapid natural aging characteristics [1][2][3]. At present, the alloy is joined by mechanical fastening method owing to the tendency for cracking in the weld metal and softening in the heat affected zone (HAZ) by conventional welding methods [4].…”

“…Un estudio realizado sobre las curvas de enfriamiento sobre perfiles tubulares o cilíndricos y perfiles de chapa llevado a cabo por (Croucher, 1987;Hall y Mudawar, 1995;Totten et al, 1996;Akbari et al, 2011), analizan la influencia del ratio de enfriamiento en función de su geometría. En los perfiles tubulares se practica un acceso por donde se introduce una sonda térmica que mide la variación térmica en el enfriamiento de la pieza desde el interior de la pieza hacia la superficie.…”

RESUMEN:Las aleaciones de aluminio se caracterizan por su bajo peso y elevada resistencia mecánica, aunque no presentan buenas propiedades mecánicas cuando son soldadas mediante arco eléctrico a excepción de las aleaciones de la serie 5XXX y serie 6XXX. En este trabajo se realiza una revisión sobre el estado del arte del ciclo térmico y la soldabilidad de las aleaciones de aluminio, mostrando las diferentes reacciones de solidificación y la influencia que presenta la velocidad de enfriamiento en las aleaciones de aluminio representado mediante las curvas de enfriamiento, evaluando su influencia sobre las propiedades mecánicas de la unión soldada. ABSTRACT: Thermal cycle and weldeability of aluminum alloys. Aluminum alloys are characterized by low weight and high strength but has not good mechanical properties when they are welded by electric arc with the exception of the series alloys 5XXX and 6XXX. This paper makes a review on the state of the art thermal cycling and weldability of aluminum alloys, showing the different reactions and the solidification influence that presents the cooling rate on aluminum alloys represented by curves cooling, evaluating in this way its influence on the mechanical properties of the welded joint. INTRODUCCIÓNEl aluminio puro es el segundo metal más abundante en la corteza terrestre y se caracteriza por ser ligero, muy blando y dúctil, pero sobre todo mecánicamente muy poco resistente y por lo tanto sus propiedades no aportan valor estructural que pueda ser utilizado en la industria. Para poder aumentar la resistencia mecánica del aluminio se empezaron a desarrollar disoluciones sólidas con varios elementos de aleación hasta obtener el duraluminio. El duraluminio hace referencia a un conjunto de aleaciones que experimentan un envejecimiento natural a temperatura ambiente que provoca un aumento considerable de su resistencia mecánica lo que permite que sea REVISIÓN

“…Quenching is usually carried out to room temperature to obtain a supersaturated solid solution of solute atoms and vacancies, in order to achieve an elevated strengthening subsequent ageing (ASM Handbook, 1991;Liščič et al, 1992;Komarova et al, 1973;Totten et al, 1998;Totten & Mackenzie, 2000). The most rapid quench rate gives the best mechanical properties, but it can also cause unacceptable amounts of distortion or cracking in components (Auburtin & Morin, 2003).…”
