How to find variation of modulus of rubber with temperature?

Click For Summary
Temperature significantly affects the modulus of rubber, as it behaves similarly to an ideal monoatomic gas, with elastic polymers not storing potential energy in stretched bonds. Instead, the work done on rubber is converted into thermal energy, influencing its elasticity. As temperature increases, the modulus of rubber typically decreases, leading to greater flexibility. The mathematical expression relating temperature and modulus can be derived from the Arrhenius equation, which describes the temperature dependence of material properties. Understanding these effects is crucial for applications involving rubber materials.

Rubber which is an elastomer behaves somewhat like an ideal monoatomic gas,
inasmuch as (to good approximation) elastic polymers do not store any potential energy in stretched chemical bonds or elastic work done in stretching molecules,
when work is done upon them. Instead, all work done on the rubber is "released" (not stored) and appears immediately in the polymer as thermal energy.

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
