[DeTomaso] Magnesium annealing- was Campagnolo Paint prep

[Larry Finch]

 Now see what you started?  :-)

I am hoping a mind brighter than mine will chime in here, but a little
research shows there are different properties for cast magnesium alloys and wrought magnesium alloys.

It appears wrought alloys may not be so content with annealing, but cast versions seem to gain benefit.

So where is the metallurgist in this forum?

I'm certainly no metallurgist, just curious. especially given the dubious nature of heating Mag into a state of white hot fire that can't be put out easily,
Where is the fine line between getting it hot and causing it to light up.
 
Just curious, I know nothing, looking to learn.
 
Thanks,

this was from the first email.

 
 
I found this online ( wiki )
 
Stages of annealing 
There are three stages in the annealing process, with the first being the recovery phase, which results in softening of the metal through removal of crystal defects (the primary type of which is the linear defect called a dislocation) and the internal stresses which they cause. Recovery phase covers all annealing phenomena that occur before the appearance of new strain-free grains.[3] The second phase is recrystallization, where new strain-free grains nucleate and grow to replace those deformed by internal stresses.[3] If annealing is allowed to continue once recrystallization has been completed, grain growth will occur, in which the microstructure starts to coarsen and may cause the metal to have less than satisfactory mechanical properties.[

Thanks for the reply, but according to what I found online, annealing
appears to make them even MORE brittle, that was
what I meant by educating me, it appears to me that the process would worsen
the condition, not improve it.

Thanks

Wellllll, since that goes against everything the De Tomaso Family has been sharing
for the last few decades, can you at least provide some links to this information
you found?

Thanks,

Larry
