Jordan Snott 4-28-22 We have 100 grams of an alloy. chemical composition of 92.4 wt. pct. tin and 8.6 wt. pct.lead. The alloy in the liquid state is cooled very slowly from 350 degrees C. At barely below 183 deg C, what are the following chemical compositions and amount in grams of: a. proeutectic a crystals. b. proeutectic ß crystals. c. eutectic a crystals d. eutectic B crystals. Lastly, Sketch the microstructure. Include labels and a scale marker.
