Thanks for the answer, yes the frames are indeed heat treated to give strength and release the stress in the welds, but having bolted areas or simply expanding and contracting every day due to the change in ambient temperature does not theoretically produce internal dislocations? For steel we...

Understood, it would be interesting to know how much stress is induced daily just due to the sudden change in temperature

Hi Berkeman, thanks for the answer, mine was a consideration, from what I read aluminum and aluminum alloys do not have a fatigue limit below which they do not register damage, at each work cycle something in the microstructure is changed. An annual thermal expansion can go from about 0° to 30°...

Hi guys, i’m always looking to conserve at best my motorcycle and car, i’m here to understand the correct way to do it

Hello, assuming to keep an aluminum alloy motorcycle frame not in use, still, will the daily temperature variations cause thermal fatigue due to the continuous expansions and retractions or is the force developed by a few degrees of variations not sufficient to create microstructural dislocations?
