Question: Composition = 99 at% Sn Composition = 99 wt% Sn Temperature = 100 deg Celsius Temperature = 212 deg fahrenheit A lead-tin alloy is slowly

Composition = 99 at% Sn Composition = 99 wt% Sn Temperature

= 100 deg Celsius Temperature = 212 deg fahrenheit A lead-tin alloy

Composition = 99 at% Sn

Composition = 99 wt% Sn

Temperature = 100 deg Celsius

Temperature = 212 deg fahrenheit

A lead-tin alloy is slowly cooled from 350C, and it is noted that the composition of the first solid a phase to solidify is 13 wt% Sn-87 wt% Pb. This alloy is further cooled to 100C. Using the Pb-Sn phase diagram (Animated Graph: Figure 10.8), calculate the mass fractions of the a and phases at 100C. Composition = Composition = Temperature = Temperature = Composition (at% Sn) 60 20 40 80 100 327 C 600 300 Liquid 500 Liquid a+L 232 C 200 a 400 183 C B+Z Temperature (C) 18.3 61.9 97.8 Temperature (F) 300 100 a + B 200 100 20 40 60 80 p (Pb) 100 (Sn) Composition (wt% Sn)
