Characterization of the Artificial Aging Behavior and Formability of a High Strength EN AW-6016 at Different Heat Treatment Conditions Used for Automotive Applications
Abstract
The growing demand for more fuel-efficient vehicles has led to a demand for sheets with higher strength accompanied by good formability to achieve a further weight reduction in cars. The purpose of this work is to investigate an alloy based on the EN AW-6016 composition which shows both, higher strength and improved formability. Within the present investigation the (I) influence of the main alloying elements of EN AW-6016 on the T4 strength and formability is described. Furthermore an (II) improved heat treatment cycle with the objective to increase both strength and formability is presented. The hereby produced T4* temper is (III) analyzed in comparison to standard T4 and other high strength Cu-containing 6xxx alloys in terms of artificial aging kinetics by using differential scanning calorimeter (DSC). Finally the (IV) effect of the improved mechanical properties on the forming performance is investigated in detail.
