I've got some samples made of aluminium alloy (HE30 BS1476)They've been solution treated at 520°C for 90 minutesWhat difference in hardness (from just after the treating) can I expect to get in one week, leaving the sample at room temperature and WHY?
Your best bet is to take a sample and send it to a labSend an original piece before solution treating then another after treating and another after one weekThe values of hardness have a range depending on the treatment process and the age of the materialSomeone might be able to ballpark a value but you won't really know what it is until you've had it tested.
