1. Answer the following questions using the phase diagram belovw Composition (at% C) 10 15 20 25 1600 1538°C 1493 C 14008 2500 1394 C 1200 1147 C 2.14 4.30 y, Austenite 2000 1000 912 C +Fe3C 800 1500 727°C 0.76 0.022 a, Ferrite 600 tite (Fe3C) 1000 400 2 6.70 0.6 (Fe) Composition (wt% C For a temperature of 1300 Celsius and a carbon wt % of 1.75, What fraction of the material will be in the Austenite phase? What fraction of the material will be in the liquid phase? What will be the carbon composition of each of the two phases? What is the eutectic temperature and eutectic composition (wt % carbon) for the austenite, liquid, Fe3C coexistence?Explanation / Answer
from the last question pont of view...
it is a temperature=1147 degree celcius
about which all three liquid ,austenite and Fe3C co-exist.
carbon percent =2.14...
just left of this pont austenit...above it liquid ...below it Fe3C
hence (temp,C%)=(1147 degree celcius, 2.14% C)
