Update. a) Since the ferrite is at the grain boundaries it can be assumed this is formed above 727 C. By inspecting the phase diagram: Hypoeutectoid begins at the austenite area, then goes to the ferrite and austenite area. Thus, the answer is hypoeutectoid. b) I just know that the answer...

Homework Statement Given that the overall weight percentage of ferrite along the grain boundaries of an as-cast steel with unknown C amount is 35.23%: a) Identify if it is hypoeutectoid or hypereutectoid. b) Identify the amount of carbon alloyed in the steel. c) Identify how much ferrite and...

Thank you sir!
