An alloy containing 10wt% Sn is cooled from 200°C to room temperature. (a) Name the major phase in the material at room temperature. (0.5 point) (b) Give the composition of this major phase at room temperature. (0.5 point) (c) On cooling to room temperature, a second phase precipitates. At what temperature does the phase diagram suggest that the second phase should appear for the first time? (0.5 point) (d) How much of the second phase is present at room temperature? (0.5 point) (e) Draw the expected microstructure at room temperature. (0.5 point) An alloy containing 10wt% Sn is cooled from 200°C to room temperature.
