How Long Should Al Alloy Ribbons Be Heat Treated?

[iti]

I am going to heat treat Al alloy ribbons of low thickness (about 0.01 to 0.025 in). Could you please suggest me the time needed for solutionising as well as aging treatment if my heat treatment cycle for thick sample is as follows?

Solutionization – 540C for 16 hrs
Quench – Room temperature water
Aging 190C for 48 hrs

Thanking You
ITI

Hi,
in my opinion you need use the same parameters.
Heat treatment main idea is the difussion of the atoms, so there is the time needed for this process.

Hello ITI,

Thank you for your inquiry. The time needed for solutionizing and aging treatment for your Al alloy ribbons will depend on several factors such as the composition of the alloy, the desired properties, and the equipment being used. However, based on the heat treatment cycle you provided, I can offer some general recommendations.

For solutionizing, a temperature of 540C and a duration of 16 hours is a common starting point for most Al alloys. However, the actual time needed may vary depending on the alloy composition and the desired microstructure. It is recommended to conduct a microstructure analysis after the solutionizing process to ensure that the desired properties have been achieved.

For aging treatment, a temperature of 190C for 48 hours is a common recommendation for Al alloys. However, this may also vary depending on the alloy composition and the desired properties. It is important to note that the aging process is time-sensitive and the microstructure and properties of the alloy can change significantly if the aging time is not precise.

Overall, I would suggest conducting some trials with different solutionizing and aging times to determine the optimal heat treatment cycle for your specific Al alloy ribbons. Additionally, it is always recommended to consult with a metallurgist or heat treatment specialist for specific recommendations based on your alloy composition and desired properties.

I hope this information helps. Best of luck with your heat treatment process.

Sincerely,
