2. (15 pts.) Bronze, the first man-made metal alloy, is formed by combining copper with tin. Cast bronze bells are manufactured by the Verdin Bells & Clocks company (htplwww.verdin.com). but even with all their experience, about 25% of bells have to be scrapped. If too much tin is combined with copper, for example, then the bell will be too brittle and break when struck For what follows, suppose bells are scrapped independently a Comsider the next thirteen bronze bells cast....

Gravimetric Analysis -- Binary Mixture Amounts of tin may be alloyed with copper to produce bronzes of varying composition and properties. 4.3330 g of a particular bronze, compounded of only Cu and Sn, can be quantitatively converted into a 5.4334-g mixture of the oxides CuO and SnO2. (Use the atomic masses: Cu 63.546, Sn 118.71, O 15.9994.) What was the percentage (by mass) of tin in the alloy?

Material Science!!!
The Cu-Sn phase diagram has historical significance as this alloy is known as bronze. The ability to make a bronze alloy changed civilization since bronze has a higher yield strength than pure copper. Cu-Sn alloys also have modern applications in electronics as a basis for the replacement of lead based solders. Answer the following questions, relative to this diagram What is the melting point of pure Cu? What is the melting point of pure Sn? What is the...

For a lead-tin alloy of composition Pb-30 wt.% Sn are heated to 300°C and slowly cooling down to room temperature. A Eutectic phase diagram of lead-tin alloy is shown in figure 3. What are the expected phases at 250°C, 150°C and at room temperature and estimate approximate phase fractions at these temperatures. Schematically draw the microstructures that would form at 250°C, 150°C and at room temperature. For a lead-tin alloy of composition Pb-30 wt.% Sn are heated to 300°C and...
