Weare interested in alloy compositions that reveal the phases y and o at JUN C. Whichalloy compositions reveal these phases ?!b) Indicate the range of alloy compositions that would reveal a microstructure consisting ofpro- eutectic & and the eutectic microstructure ."C ) An alloy contains 60 wt %/ pro- eutectic & and 40%/ eutectic y + 6 at I < 4370 C . Determinethe composition of this alloy .\d ) Which alloy compositions will have no eutectic microstructure but still exhibit the twophase mixture of Y and S ?Draw the microstructure of these alloy compositions ."@ ) Which alloy composition will exhibit pro- eutectic y and 20% of eutectic microstructurejust below 4370 C ?`I )The alloy composition of 10 wt%/! My is being heated to the liquid phase andthenquenched from 700 ' C to 100'C . What type of solid material will result ?"8 ) The same alloy composition is heated to 400' C and cooled slowly to 100'C .
