Select the correct definition for normalising.
The rapid cooling of a hot metal by immersing it in a liquid
A heat treatment that increases the hardness and strength of a metal due to a chnage in the arrangement of atoms within it.
A heat treatment process to remove brittleness in hardened steel, at the cost of some hardness.
A heat treatment csrried out on steel that has been owrk hardened this process involves heating steel to its upper critical point and allowing to coll naturally in air.
A process that involves heating a metal to a suitable temperature to make it softer and easuer to work. It is used to soften work hardened metal or to make metals easier to bend into complicated shapes.
Select the correct definition for annealing.
