: For Steel At Temperature Just Above 727 C Eutectoid Isotherm If The Fraction Of Austenite Is 93 What Could Be The 1 (62.94 KiB) Viewed 38 times

For steel, at temperature just above 727°C (eutectoid isotherm), if the fraction of austenite is 93%, what could be the other phase and how much is its fraction? What is the percent of carbon inside the steel? For the solution of this problem, please take note there may be more than one combination of binary phases.
Calculate the fraction of each phases of steel composed of iron and 0.8% carbon just below the eutectoid isotherm (727°C). Express your answers in terms of binary phases of ferrite and cementite. If pearlite is considered as one phase, what is its fraction in the system?
