Weaker hard ferrite (iron-oxide) permanent magnets typically max out at around 0.35 tesla. The world's strongest permanent magnets made of neodymium measure around 1.4‑1.6 teslas. Niron’s ...

The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> Ferrite + Cementite Austenite is stable above 727 C and is an interstitial solid solution of ...
