Quenching Aluminum for Residual Stress and Distortion Control ∗
Abstract: The heat treatment of aluminum (Solution Heat Treatment, Quenching and Aging) are critical processes to insure that the desired mechanical and corrosion properties are achieved. Of these steps, quenching is perhaps the most critical of all the operations. If quenching is too fast, properties are met, but the part may have excessive distortion or residual stresses. This can result in shortened life due to residual stresses, or result in additional non-value added straightening of the component and this increases cost and cycle time. In this paper, the mechanism for distortion of aluminum is explained, and methods (racking and quenchants) are shown that can reduce distortion and residual stresses in heat treated components.
Die Wärmebehandlung von Aluminium (Lösungsglühen, Abschrecken und Altern) ist ein kritischer Prozess, um sicherzustellen, dass die gewünschten mechanischen und Korrosionseigenschaften erreicht werden. Von diesen Schritten ist das Abschrecken möglicherweise der kritischste aller Vorgänge. Wenn das Abschrecken zu schroff ist, werden die Eigenschaften zwar erfüllt, das Bauteil kann jedoch übermäßige Verzüge oder Eigenspannungen aufweisen. Dies kann zu einer verkürzten Lebensdauer aufgrund von Eigenspannungen oder zu einem zusätzlichen, nicht wertschöpfenden Richten des Bauteils führen. Hierdurch erhöhen sich die Kosten und die Zykluszeit. In dieser Arbeit wird der Mechanismus der Verformung von Aluminium erläutert und es werden Methoden (Chargierung und Abschreckmedium) gezeigt, mit denen Verformungen und Eigenspannungen in wärmebehandelten Bauteilen verringert werden können.
