Hello guys,
I'm doing a failure analisys on an aluminum 7075 T6. I think the failure mode is brittle. Attached the SEM image.
The supplier send the "recipe" for the T6. What do you think about this recipe?
Solution Heat treatment: 470°C(880F) - 2h - water cooling
Precipitation: 120°C(250F)2h + 180°C(360F)
Recristalization: 260°C(500F) - 3h - air cooling
Some times they do the T6 twice. Do you think this is a problem?
