Answer 2

Answer:

Ferrite

Explanation:

Ferrite is referred to as α stable answer. It is an interstitial stable answer of a small quantity of carbon dissolved in α (BCC) iron. The most solubility is 0.025 t 723C and it dissolves best 0.008 t room temperature. It is the softest shape that looks at the diagram.

Ferrite incorporates little or no or no carbon in iron. It is the call given to natural iron crystals which can be gentle and ductile. The gradual cooling of low carbon metallic underneath the essential temperature produces ferrite shape. Ferrite does now no longer harden whilst cooled rapidly. It may be very gentle and fairly magnetic.
