Quenching and partitioning is an operation used in develop of TRIP, AHSS steels with the whole point of inducing more than one phase. However can't it be applied to precipitation hardenable aluminum alloys to induce and stabilize the precipitates.
In Q and P, interstitial element C, which is in supersaturated state diffuse to another phase which can have higher solubility for it. You can try this with two phase Al alloy. But in PH Al alloys for eg. Al-Cu system, Cu cause the supersaturation but it is not an interstitial element to diffuse easily. Also there is no second phase which can take excess Cu.
Akeshwar Singh Yadav . Thank you very much for your answer. Yes I was looking at the 2xxx series when the idea came to me. However I think there is a point I missed when I thought of using Q and P to replace the PH process.
Nevertheless, thanks for your response. Will still look at it and see what will happen if I introduce an interstitial element.
