Paint Bake Cycle<br />

18<br />

Al alloys used for automotive applications undergo<br />

a paint bake cycle which may have an effect on<br />

the material’s properties given that many Al alloys<br />

are artificially aged around this temperature<br />

Baking Conditions:<br />

180°C for 20 mins then air cool, reheat to 180°C for 30 mins<br />

All base material samples with the exception <strong>of</strong><br />

5754-O tested in this condition<br />

All welds were tested in this condition which is<br />

meant to simulate the paint bake cycle.
