For the phase transformation diagram below the material is a

For the phase transformation diagram below, the material is an iron-carbon alloy with cutectoid composition. Specify the nature of the final microstructure (% bainite, martensite, pearlite, etc.) for the alloy that is subjected to the following time-temperature treatments: Alloy begins at 760 degree C and has been held long enough to achieve a complete and homogenous austenitic structure. Rapidly cool to 650 degree C Hold for 20 seconds Rapidly cool to 400 degree C Hold for 10^3 seconds Quench to room

Solution

Given is the description of phase transformation diagram. What is to be calculated.
