What the definition of critical cooling rate in a context of austenite transformation?
The slowest rate of cooling from the hardening temperature which will produce the fully hardened martensitic condition.

What is austenite?
its a solid solution created when carbon steel is heated to red hot. also know as the alpha iron. during cooling of the steel it can transform into pearlite or ferite.

Why is austenite magnetic?
Austenite is not magnetic. It's an allotrope of iron, and has some alloying agents, but it only exists at high temperatures that are well above the Curie point of whatever iron alloy is heated. We...

Difference between coarse pearlite and fine pearlite?
coarse pearlite structure has better ductility and toughness compared to fine pearlite structure but fine pearlite structure has better strength compared to coarse pearlite structure.
