Abstract
The aluminium alloy AW-6016-T4 sheet is the most widely used alloy for simple-shapeouter body parts for passenger vehicles at room temperature. However, for complex parts, such asthe B-pillar, the room temperature formability of AW-6016-T4 sheet is not sufficient. Simultaneoushot stamping and quenching is a viable alternative, but there is still limited information about theinfluence of process parameters on both the formability during the process and the part strength atthe end of the process. A combination of thermo-kinetic simulation and experiments were used toinvestigate the influence of process parameters in the simultaneous hot stamping and quenchingprocess.Increasing the heating rate from 1 to 100 K s-1 during heating to the solution heat treatment (SHT)temperature was found to have no significant influence on the UTS. However, a SHT time of 4 minis required to achieve highest strength by the end of the process chain. Increasing the amount ofdeformation and cooling rate after SHT have a positive influence on the finished part. PredictedDSC curves and Yield strength values from MatCalc were in good agreement with the experimentalresults.
