Abstract
The effects of thermal treatments in a component for automotive industry are considered: the induced residual stresses in wheel hubs were investigated. Measurements have been carried out on two identical simple shape demonstratorsmadeofAA6061+22%Al2O3pinordertoevaluatethestressconditionsafterforgingandT6treatment and without taking into account the final design of the wheel hub. One sample was analysed in as-forged conditions while the second after forging and T6 treatment (560C for 2h, 20C water quenching, artificial aging at 177C for 10 h). Particular attention was given to the stresses in the radial and hoop directions, as the main consequences of the in-service fatigue are expected to be related to stresses along these two directions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
