Crack-fabrication techniques and their effects on the fracture ...

A drill of 1.95 mm diameter was used to drill a small hole at the notch root of the specimens of group A (of a crack initially formed using a band saw). The average root radius was measured to be 1.1 ± 0.08 mm. The notches in the specimens of group B were simply cut by a band saw, resulting in a rectangular-ended root of width 1.8 ±0.2 mm.

What would happen if the Earth's core turned to gold? - Quora

We would all freeze at close to absolute zero. The fusion of atomic nuclei with more than 26 protons (iron) absorbs energy. That is why it doesn't happen except in exceptional cases like supernova or colliding neutron stars. Fusion to gold with 79 protons would absorb a lot of energy and the whole Earth would freeze.
