When my engine swallowed and apex seal, a piece of it flew back and got squished by the next apex seal area and actually caused a corner of the rotor to crack.  So it appeared to be harder than the rest of the rotor which was soft enough for the metal to smear.  Interesting videos for sure, thanks for sharing, Marc

Interesting. I never heard about the high frequency RF hardening of the apex
seal slot area before.....!

Fellow RE enthusiast.

Mazda Japan has released a very interesting set of small videos that detail
how it creates and builds its Rotary Engines.
