Yup. The bubbles coupled with the extreme heat actually cause a sublimation
(direct change for solid to gas phase) effect in the steel. Because of the
austenitic nature of the substrate, there is severe weakening of the metal in
the area of the friction induced heat, e.g. the hole.
(I made that up; waiting for my lunch. Idle mind and all that)
