Heat Treatment of Carbon Steels

The purpose of heat treatment of carbon steel is

The microstructure in annealed carbon steel is

Cooling down austenite by moderate cooling rate forms

Carbon steel tempering should take place

Which of the following microstructures in carbon steel is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (88 wt. %) and cementite (12 wt. %)?

When austenite is cooled down at a very high rate by quenching, its FCC structure will transform to Body Centred Tetragonal (BCT) known as

Which of the followings in carbon steel is an extremely hard and brittle phase which lacks toughness so it should be tempered?
