On the same note, thermal expansion...

Presumably as the core solidifies (cools down) it would contract, would
it not?, what effect would that have on the crystalline structure
(widmanstatten) would there be a gradual stress/distortion in the
taenite/kamacite boundries ?=20


I guess as the core is such a big mass, any significant thermal
contraction distortion would hardly be noticeable in a small hand
specimen but I would imagine the thermal contraction in something the
size of a large planetary body would be massive.
