As received sample is rolled well in 10 passes with 5% reduction in each pass while its breaking after solution heat treatment like brittle material in one or two passes.
It is advisable to process the heat treatable aluminium alloys as soon as possible after solution treatment (with in ~4 hrs) to complete the process before the precipitation hardening starts.
If you are following this, then please check the material for any inclusions which might have caused brittleness in alloy.
Hope this will help you.
There could be several reasons why an aluminum alloy breaks after solution heat treatment during rolling in one or two passes, while it rolls well in the as-received condition. Here are a few possible explanations:
To determine the exact cause of the cracking, it would be necessary to perform a detailed analysis of the alloy and the processing conditions.
