This is just a wild thought, but what if the boiling process doesn't alter
the the strength of the material, but helps to reduce stress concentration
points?
If the gear deforms ever so slightly (i.e. negligible deformation- no change
when viewed with the human eye), perhaps microscopic cracks and other
geometric irrgularities are "filled in" and smoothed over. This will
increase the strength of the gear, but not significantly.
Your test only demonstrates the strength of the boiled gear relative to the
non-boiled gear. It doesn't measure a magnitude of increased strength.
Perhaps the boiled gear is just slightly stronger?
I dunno. Just thinkin'...
