Abstract
For HFQ volume production in automotive applications, short heat treatment
time is an important factor for efficient and cost effective manufacturing. In this study,
fast, efficient and energy saving solution heat treatment (SHT) and ageing processes have
been identified based on precipitation nucleation and growth mechanisms and a series of
experiments. Material chosen was AA6082, which is an alloy favoured for automotive body
structures. The effects of heating rate, soaking temperature and time on SHT processes,
and the influence on post mechanical properties, have been characterised. A duplex
ageing process integrated paint bake process has been developed, with an optimum ageing
condition determined. In addition, the effect of pre-deformation has been analysed.
