The following figures and tabulated data were obtained during the Phase diagram experiment for Pb Sn using DSC machine Tables 14 shows the wt% composition of Sn in Pb at 1 Use figures

The following figures and tabulated data were obtained during the Phase diagram experiment for Pb-Sn using DSC machine. Tables 1-4 shows the wt% composition of Sn in Pb at 1) Use figures 1 and 2, and Table 1 to plot the Temperature 2) Use the figures 1 and 2, and Table 2 to plot the different temperatures (°C) against wt% composition of Sn in Pb Temperature (°C) against wt% composition of Sn in Pb on the same graph obtained from (1) above 3) Use Table 3 to plot the Temperature (°C) against wt% composition of Sn in Pb on the same graph obtained from (2) above 4) Use Table 4 to plot the Temperature (°C) against wt% composition of Sn in Pb on the same graph obtained from 5) Determine the eutectic wt% composition and Temperature 6) What is the temperature at which 80wt%Pb-20wt%Sn will 7) What is the temperature at which 86wt%Pb-14wt%Sn will 8) At 50 °C, what will be the wt% compositions on the solvus 9) What is the wt% compositions of α and L at 80wt%Pb- (3) above.
