From an iron-carbon phase diagram, plotted in terms of weightpercent carbon:
A) What is the composition in weight percent of the iron-carbonalloy that has the lowest melting temperature? What is this meltingtemperature?
B) What is the composition in weight percent of the iron-carbonalloy that has the eutectoid composition? What is the eutectoidtemperature?
C) What is the lowest temperature and weight percent carbon atwhich any iron-carbon alloy shows any amount of delta phase?
D) A particular iron-carbon alloy shows a final microstructureafter slow cooling that consists of 80% proeutectoid ferrite and20% pearlist. What is the carbon composition of this alloy, inweight percent?
E) At what temperature would the alloy from part d become allsingle-phase austentite on heating?
F) At what temperature would the alloy from part d become allliquid on heating?
