Cool video: Ceramic head cuts one of the toughest metals in the world

That fully grown block of metalis inconel , an extremely tough “ austenitic nickel - chromium - based superalloy , ” one of the strong metals know to humans , used in “ in extreme environments subject to pressure and heat ” like nuclear plant . How do you cut such a hard affair ? Let ’s watch a video .

That ’s a ceramic head rotating at very in high spirits speed . There are other ways — like piss cutters — but only ceramic cutters can machine inconel at high speed .

When heat , Inconel forms a dense , stable , passivating oxide layer protecting the open from further attack . Inconel retain forte over a wide temperature range of mountains , attractive for in high spirits temperature software where aluminum and steel would succumb tocreepas a answer of thermally - induced crystal vacancies ..
