WebNov 27, 2024 · According to the Iron-Carbon phase diagram, we call the composition of steel that contains 0.8 percent of carbon as eutectoid composition. It is a certain composition where, upon cooling austenite to lower than 723°C (eutectoid reaction), the austenite turns into pearlite (alternate layers of ferrite and cementite). WebWhich of the following statements are correct regarding the austenite phase in an iron-carbon phase diagram? a. It is non-magnetic in nature: b. The maximum percentage of carbon is 2.1%: c. It has a face-centered cubic structure: d. The austenitic phase has a face-centered cubic structure with a 2.1% maximum percent carbon and non-magnetic in ...
