Answer 1

Answer:

Martensite is super saturated solution of carbon in Alpha iron. It is diffusion less process and marten site has BCT(Body Centered Tetragonal structure).

Answer 2

Martensite is a super saturated solution of carbon in Alpha iron.

Explanation:

• Martensite is the hardest form of  steel.
• It is tetragonal structure of iron.
• In this structure the carbon is dissolved.
• To make martensite,the steel is heated to very high temperature which in turn produces austenite.
• When this austenite undergoes immediate cooling phase, it results in the formation of martensite.
• Alpha iron is a iron allotrope with body-centered cubic structure.
• It is stable below at 910°C and stable at room temperature.
• At 912°C, the molten iron is cooled and alpha iron is formed.
