Characterization and Optimized Ageing Parameters of Aluminium Alloy AA6110

Abstract:

Copper containing aluminium alloy AA6110 is introduced to automotive industries for the last few decades. An understanding of its precipitation sequence and mechanical properties during ageing treatment is valuable to optimize some heat treatment processes in the automotive manufacturing. Therefore, in this study, the precipitation sequence, microstructures and mechanical properties of copper containing aluminium alloy AA611 were investigated. A differential scanning calorimeter (DSC) with regular heating rate of 10 °C/min was performed on the solid solution heat treated aluminium alloy AA6110 for the precipitation sequence investigation. Solid solution heat treated samples were aged at different temperatures and times. Hardness values of differently aged aluminium alloy AA6110 were measured to determine optimized parameters of the ageing process. It was found that the maximum hardness value of 141 HV was detected at an ageing temperature of 160 °C for about 12 hr. Tensile properties and microstructures using transmission electron microscope (TEM) of specimens aged at a temperature of 160 °C with different ageing time will be investigated and shown.
